Step-by-step solution for: Math Logic Problems
Let's solve the logic puzzle "Who Chose Which Shape? #2" step by step using the clues.
We have five salamanders:
- Captain
- Frazer
- Tyger
- Sally
- Flame
And five shapes:
- A) Pentagon (5 sides, regular)
- B) Right triangle (3 sides, one right angle)
- C) Parallelogram (4 sides, no right angles, opposite sides equal)
- D) Rectangle (4 sides, all angles right angles)
- E) Irregular pentagon (5 sides, bent shape)
---
1. Captain’s shape has 4 sides.
2. Frazer’s shape has just one line of symmetry.
3. Tyger’s shape has more than 4 sides.
4. Sally’s shape has sides all the same length.
5. Flame’s shape has more than one right angle.
We’ll go through each clue and eliminate possibilities.
---
So Captain must have a shape with exactly 4 sides.
Shapes with 4 sides:
- C) Parallelogram
- D) Rectangle
(Both are quadrilaterals.)
So Captain → C or D
---
Let’s examine symmetry in each shape:
- A) Regular Pentagon: 5 lines of symmetry → ✘
- B) Right triangle (scalene): Usually 0 lines unless isosceles. But this looks like a scalene right triangle → likely 0 lines → ✘
Wait — actually, if it's a right triangle with two equal sides, it would have 1 line of symmetry. But from the drawing, it looks like a standard right triangle with legs of different lengths → so no symmetry → 0 lines → ✘
- C) Parallelogram: No line of symmetry (unless rhombus or rectangle) → This one is slanted → no symmetry → 0 lines → ✘
- D) Rectangle: 2 lines of symmetry (vertical and horizontal) → ✘
- E) Irregular pentagon: Looks like a "C" shape, not symmetric → 0 lines → ✘
Wait! That’s a problem. None seem to have exactly one line of symmetry?
But let's double-check.
Hold on — B) is a right triangle. If it's isosceles right triangle, it has one line of symmetry — the diagonal from the right angle to the midpoint of the hypotenuse.
Looking at the image: It appears to be a right triangle, but does it have two equal sides?
From the drawing: The two legs look different — one is longer than the other. So probably not isosceles → no symmetry.
But maybe we’re missing something.
Wait — Shape C: Parallelogram — if it's not a rhombus or rectangle, it has no lines of symmetry.
Shape D: Rectangle — 2 lines of symmetry.
Shape A: Regular pentagon — 5 lines.
Shape E: Irregular — probably none.
So which shape has exactly one line of symmetry?
Hmm. Maybe B is intended to be an isosceles right triangle? Even if it doesn’t look perfectly symmetrical, perhaps that’s the intention.
Alternatively, could E have one line of symmetry?
Look at E: It’s a pentagon shaped like a "C" — bent inward. Does it have any symmetry? Probably not.
Wait — maybe C is a rhombus? But it’s drawn as a parallelogram, not necessarily a rhombus.
But none of these shapes appear to have exactly one line of symmetry.
Wait — let's re-express the options:
Let’s analyze each shape:
- A) Regular pentagon: 5 lines of symmetry → too many
- B) Right triangle: If it's not isosceles, 0 lines; if isosceles, 1 line → but drawing suggests it's not isosceles → so probably 0
- C) Parallelogram: 0 lines (unless rhombus or rectangle)
- D) Rectangle: 2 lines
- E) Irregular pentagon: 0 lines
So only possibility for one line of symmetry is if B is an isosceles right triangle.
But it’s drawn as a right triangle with unequal legs.
Wait — maybe E is symmetric? Let’s look again.
Shape E: It looks like a pentagon with a "bite" taken out — kind of like a "C" — but not symmetric.
Alternatively, maybe C is a kite? But it’s drawn as a parallelogram.
Wait — perhaps I'm overcomplicating.
Let’s try another approach.
Maybe Frazer’s shape has just one line of symmetry, and among the shapes, only one fits that.
Let’s suppose B is intended to be an isosceles right triangle — then it has one line of symmetry.
That seems plausible.
So assume B has one line of symmetry.
So Frazer → B
But wait — is that the only one?
What about A? Regular pentagon has 5 lines → no.
C: Parallelogram — if it's a rhombus, it has 2 lines of symmetry — but it’s not drawn that way.
D: Rectangle — 2 lines → no.
E: Irregular — no.
So only B can possibly have one line of symmetry if it’s isosceles.
So likely: Frazer → B
Let’s tentatively assign:
> Frazer → B (Right triangle, assuming isosceles)
Now proceed.
---
So Tyger → shape with 5 or more sides
Only shapes with more than 4 sides:
- A) Pentagon (5 sides)
- E) Irregular pentagon (5 sides)
So Tyger → A or E
---
So it’s equilateral.
Which shapes have all sides equal?
- A) Regular pentagon → yes, all sides equal
- B) Triangle — unless equilateral — but it's a right triangle → cannot have all sides equal (hypotenuse is longer) → no
- C) Parallelogram — not necessarily — but this one looks like a rhombus? But it’s drawn as a slanted rectangle — not clear
- D) Rectangle — only if square, but not drawn as square — sides look different
- E) Irregular pentagon — clearly not
So only A has all sides equal (regular pentagon)
Therefore:
> Sally → A
Now we know:
- Sally → A
- Tyger → A or E → but A is taken → so Tyger → E
So:
> Tyger → E
Now back to Captain: must have 4 sides → C or D
Remaining shapes: C, D, B
But B is assigned to Frazer.
So shapes left: C and D
Salamanders left: Captain, Flame
Clue 1: Captain → 4 sides → C or D → both are 4-sided → so either possible
Clue 5: Flame’s shape has more than one right angle
Let’s check:
- C) Parallelogram: no right angles → 0
- D) Rectangle: 4 right angles → yes, more than one → fits
- B) Right triangle: only 1 right angle → not enough
- A) Pentagon: no right angles
- E) Irregular pentagon: may have some, but hard to tell — but from drawing, it has sharp bends, but no obvious right angles
So only D has more than one right angle → 4 right angles
So Flame → D
Then remaining shape is C, and remaining salamander is Captain
So Captain → C
Now let’s summarize:
| Shape | Salamander |
|-------|------------|
| A) Pentagon | Sally |
| B) Triangle | Frazer |
| C) Parallelogram | Captain |
| D) Rectangle | Flame |
| E) Irregular pentagon | Tyger |
Now verify all clues:
1. Captain’s shape has 4 sides → C is a parallelogram → 4 sides → ✔
2. Frazer’s shape has just one line of symmetry → B is a right triangle — but only if it’s isosceles. Is it?
Wait — here’s a problem.
If B is a scalene right triangle, it has no lines of symmetry.
But clue says Frazer’s shape has just one line of symmetry.
So unless B is isosceles, this fails.
But in the diagram, B looks like a right triangle with two different-length legs → so not isosceles → 0 lines of symmetry
But we need one line of symmetry.
So contradiction.
So our assumption must be wrong.
Alternative: Maybe C has one line of symmetry?
But C is a parallelogram — unless it's a rhombus, it has no symmetry.
But it’s drawn as a skewed rectangle — not symmetric.
Wait — what about D? Rectangle → 2 lines of symmetry → not “just one”
A → 5 lines → no
E → irregular → no
So none of the shapes have exactly one line of symmetry?
That can't be.
Wait — perhaps E has one?
Look at E: It’s a pentagon that looks like a "C" shape — bent inward.
Does it have a line of symmetry?
No — it's not symmetric.
Wait — perhaps C is a kite? But it’s drawn as a parallelogram.
Wait — let's re-examine the shapes.
Wait — maybe C is a rhombus? But it’s drawn with parallel sides, but not necessarily equal.
But still — a rhombus has 2 lines of symmetry.
Not one.
Wait — perhaps B is intended to be an isosceles right triangle, even if it doesn’t look perfectly symmetrical.
That’s the only way clue 2 makes sense.
Alternatively, maybe C is a parallelogram that is not symmetric, so 0 lines.
Wait — what if E has one line of symmetry?
Look at E: It’s a five-sided shape with a concave part.
It might be symmetric along a vertical axis?
Let me describe it: It looks like a pentagon with a "bite" taken out on the right side — forming a "C" shape.
But the two ends are not symmetric — the top and bottom are different.
So probably no symmetry.
Wait — perhaps D is a square? But it’s drawn as a rectangle — longer than wide.
But if it were a square, it would have 4 lines of symmetry — not one.
No.
Wait — maybe C is a kite?
But it’s drawn as a parallelogram — opposite sides parallel.
A kite has two pairs of adjacent equal sides, but not opposite.
So not a kite.
This is confusing.
Wait — perhaps I misread the shapes.
Let’s list the shapes again:
- A) Regular pentagon — 5 sides, all equal, 5 lines of symmetry
- B) Right triangle — 3 sides, one right angle
- C) Parallelogram — 4 sides, opposite sides parallel and equal, no right angles
- D) Rectangle — 4 sides, all angles right angles
- E) Irregular pentagon — 5 sides, concave, bent
Now, which of these has exactly one line of symmetry?
Only possible candidate: B, if it’s isosceles right triangle.
Even if it looks scalene, maybe it’s intended to be isosceles.
In many such puzzles, the right triangle is assumed to be isosceles when symmetry is required.
So let’s assume B is an isosceles right triangle → has one line of symmetry → ✔
So Frazer → B
Now continue.
We had:
- Sally → A (all sides equal) → ✔
- Tyger → E (more than 4 sides) → ✔
- Flame → D (more than one right angle) → ✔
- Captain → C (4 sides) → ✔
Now check Flame: D is a rectangle → has four right angles → more than one → ✔
Captain: C is a parallelogram → 4 sides → ✔
But wait — C is a parallelogram — does it have any right angles? No — it’s drawn without right angles.
But that’s fine — clue only says Captain’s shape has 4 sides — doesn’t require right angles.
So okay.
Now, Frazer → B → isosceles right triangle → one line of symmetry → ✔
Sally → A → regular pentagon → all sides equal → ✔
Tyger → E → 5 sides → more than 4 → ✔
All clues satisfied.
But earlier concern: is B really isosceles?
Perhaps the drawing is approximate.
Alternatively, maybe C has one line of symmetry?
No — a general parallelogram has no lines of symmetry.
Unless it’s a rhombus or rectangle.
But it’s not.
So only B works.
Thus, final assignment:
| Shape | Salamander |
|-------|------------|
| A) Pentagon | Sally |
| B) Triangle | Frazer |
| C) Parallelogram | Captain |
| D) Rectangle | Flame |
| E) Irregular pentagon | Tyger |
Now write the names under the shapes:
- A) Sally
- B) Frazer
- C) Captain
- D) Flame
- E) Tyger
---
A) Sally
B) Frazer
C) Captain
D) Flame
E) Tyger
✔ All clues satisfied.
Let’s verify once more:
1. Captain’s shape has 4 sides → C is parallelogram → 4 sides → ✔
2. Frazer’s shape has just one line of symmetry → B is isosceles right triangle → 1 line → ✔
3. Tyger’s shape has more than 4 sides → E is pentagon → 5 sides → ✔
4. Sally’s shape has sides all the same length → A is regular pentagon → all sides equal → ✔
5. Flame’s shape has more than one right angle → D is rectangle → 4 right angles → ✔
Perfect!

2. Frazer’s shape has just one line of symmetry.
3. Tyger’s shape has more than 4 sides.
4. Sally’s shape has sides all the same length.
5. Flame’s shape has more than one right angle.
We’ll go through each clue and eliminate possibilities.

Clue 1: Captain’s shape has 4 sides.
So Captain must have a shape with exactly 4 sides.
Shapes with 4 sides:
- C) Parallelogram
- D) Rectangle
(Both are quadrilaterals.)
So Captain → C or D

Clue 2: Frazer’s shape has just one line of symmetry.
Let’s examine symmetry in each shape:
- A) Regular Pentagon: 5 lines of symmetry → ✘
- B) Right triangle (scalene): Usually 0 lines unless isosceles. But this looks like a scalene right triangle → likely 0 lines → ✘
Wait — actually, if it's a right triangle with two equal sides, it would have 1 line of symmetry. But from the drawing, it looks like a standard right triangle with legs of different lengths → so no symmetry → 0 lines → ✘

But maybe we’re missing something.
Wait — Shape C: Parallelogram — if it's not a rhombus or rectangle, it has no lines of symmetry.
Shape D: Rectangle — 2 lines of symmetry.
Shape A: Regular pentagon — 5 lines.
Shape E: Irregular — probably none.
So which shape has exactly one line of symmetry?
Hmm. Maybe B is intended to be an isosceles right triangle? Even if it doesn’t look perfectly symmetrical, perhaps that’s the intention.
Alternatively, could E have one line of symmetry?
Look at E: It’s a pentagon shaped like a "C" — bent inward. Does it have any symmetry? Probably not.

So only possibility for one line of symmetry is if B is an isosceles right triangle.
But it’s drawn as a right triangle with unequal legs.

Shape E: It looks like a pentagon with a "bite" taken out — kind of like a "C" — but not symmetric.

So likely: Frazer → B
Let’s tentatively assign:
> Frazer → B (Right triangle, assuming isosceles)
Now proceed.
---
Clue 3: Tyger’s shape has more than 4 sides
So Tyger → shape with 5 or more sides
Only shapes with more than 4 sides:
- A) Pentagon (5 sides)
- E) Irregular pentagon (5 sides)
So Tyger → A or E
---
Clue 4: Sally’s shape has all sides the same length
So it’s equilateral.
Which shapes have all sides equal?
- A) Regular pentagon → yes, all sides equal
- B) Triangle — unless equilateral — but it's a right triangle → cannot have all sides equal (hypotenuse is longer) → no
- C) Parallelogram — not necessarily — but this one looks like a rhombus? But it’s drawn as a slanted rectangle — not clear
- D) Rectangle — only if square, but not drawn as square — sides look different
- E) Irregular pentagon — clearly not
So only A has all sides equal (regular pentagon)
Therefore:
> Sally → A
Now we know:
- Sally → A
- Tyger → A or E → but A is taken → so Tyger → E
So:
> Tyger → E
Now back to Captain: must have 4 sides → C or D
Remaining shapes: C, D, B
But B is assigned to Frazer.
So shapes left: C and D
Salamanders left: Captain, Flame
Clue 1: Captain → 4 sides → C or D → both are 4-sided → so either possible
Clue 5: Flame’s shape has more than one right angle
Let’s check:
- C) Parallelogram: no right angles → 0
- D) Rectangle: 4 right angles → yes, more than one → fits
- B) Right triangle: only 1 right angle → not enough
- A) Pentagon: no right angles
- E) Irregular pentagon: may have some, but hard to tell — but from drawing, it has sharp bends, but no obvious right angles
So only D has more than one right angle → 4 right angles
So Flame → D
Then remaining shape is C, and remaining salamander is Captain
So Captain → C
Now let’s summarize:
| Shape | Salamander |
|-------|------------|
| A) Pentagon | Sally |
| B) Triangle | Frazer |
| C) Parallelogram | Captain |
| D) Rectangle | Flame |
| E) Irregular pentagon | Tyger |
Now verify all clues:
1. Captain’s shape has 4 sides → C is a parallelogram → 4 sides → ✔
2. Frazer’s shape has just one line of symmetry → B is a right triangle — but only if it’s isosceles. Is it?
Wait — here’s a problem.
If B is a scalene right triangle, it has no lines of symmetry.
But clue says Frazer’s shape has just one line of symmetry.
So unless B is isosceles, this fails.
But in the diagram, B looks like a right triangle with two different-length legs → so not isosceles → 0 lines of symmetry
But we need one line of symmetry.
So contradiction.
So our assumption must be wrong.

No.

A kite has two pairs of adjacent equal sides, but not opposite.

So okay.
Now, Frazer → B → isosceles right triangle → one line of symmetry → ✔
Sally → A → regular pentagon → all sides equal → ✔
Tyger → E → 5 sides → more than 4 → ✔
All clues satisfied.
But earlier concern: is B really isosceles?
Perhaps the drawing is approximate.

No — a general parallelogram has no lines of symmetry.
Unless it’s a rhombus or rectangle.
