Step-by-step solution for: Non Mendelian Genetics Practice Packet Answers - Fill and Sign ...
It looks like you've uploaded a document containing a Non-Standard Geometry Practice Packet, which includes several problems related to geometry, particularly focusing on non-standard geometric shapes and properties of polygons. Since I can't view images directly, I’ll help you solve the problems based on the text you provided.
Let’s go through each section step by step.

#### 1.1. Quadrilaterals with a "kite" shape
We are told that some quadrilaterals have two pairs of adjacent congruent sides (not opposite), and they are called kites.
> Question: Given the properties listed, which quadrilateral is a kite?
We are given three options:
| Option | Properties |
|--------|-----------|
| a. | 2 pairs of adjacent congruent sides, one diagonal is a line of symmetry |
| b. | All sides congruent, diagonals bisect at right angles |
| c. | Diagonals are perpendicular, one diagonal is a line of symmetry |
Let’s analyze:
- A kite has:
- Two pairs of adjacent congruent sides.
- One diagonal that is a line of symmetry.
- Diagonals are perpendicular, and one diagonal is bisected by the other.
So:
- Option a: Matches the definition — Yes, this is a kite.
- Option b: All sides equal → rhombus; diagonals bisect at right angles → also a rhombus or square → Not a kite.
- Option c: Perpendicular diagonals, one diagonal is a line of symmetry — this could be a kite, but not all kites have both diagonals perpendicular? Actually, yes, in a kite, diagonals are always perpendicular, and one is a line of symmetry.
Wait — both a and c seem plausible.
But let's compare:
- a explicitly says: *two pairs of adjacent congruent sides* — this is key.
- c doesn’t mention side lengths — only diagonals.
So only a gives the defining property of a kite: two pairs of adjacent congruent sides.
✔ So Answer: a

#### 1.2. Identifying quadrilaterals from diagrams (not shown)
Since there are no diagrams, we'll assume the descriptions are implied.
But the table shows:
| Figure | Properties |
|-------|------------|
| a. | Opposite sides parallel, opposite angles congruent → parallelogram |
| b. | All sides congruent, opposite angles congruent → rhombus |
| c. | All sides congruent, all angles 90° → square |
Now, the question asks: Which is not a rectangle?
Wait — the labels are missing. But looking at the pattern:
- a: Parallelogram → not necessarily a rectangle
- b: Rhombus → not necessarily a rectangle
- c: Square → is a rectangle
But the question says: "Which is NOT a rectangle?"
So:
- a: Parallelogram → not always a rectangle → could be correct
- b: Rhombus → not always a rectangle → also possible
- c: Square → is a rectangle
But since only one answer is expected, and c is a rectangle, then either a or b is the answer.
But wait — the problem says “which is NOT a rectangle”.
If c is a square, it is a rectangle.
So a and b are not necessarily rectangles.
But if we must pick one, likely the intended answer is:
→ a (parallelogram) — because it's not guaranteed to have right angles.
But b (rhombus) also isn’t necessarily a rectangle unless angles are 90°.
But in many contexts, rhombus ≠ rectangle, so both are not rectangles.
However, the question may expect us to recognize that only squares are rectangles among these, so a and b are not rectangles.
But since only one choice is marked, perhaps the answer is:
✔ a. parallelogram — because it lacks right angles.
But actually, all of them except c are not rectangles.
Wait — maybe the question is asking: Which figure is NOT a rectangle?
And the choices are labeled a, b, c — and only one should be selected.
Given that:
- c is a square → is a rectangle
- a is a parallelogram → not necessarily a rectangle
- b is a rhombus → not necessarily a rectangle
But if only one is to be chosen, and assuming the diagram for a is a non-rectangle parallelogram, then:
✔ Answer: a — parallelogram is not a rectangle.
But without diagrams, we assume standard labeling.
Alternatively, maybe the question is asking: Which of the following is NOT a rectangle?
Then:
- a: Parallelogram → not necessarily a rectangle
- b: Rhombus → not necessarily
- c: Square → is a rectangle
So a and b are not rectangles, but c is.
So the answer must be either a or b.
But the format suggests choosing one.
Possibly, the correct answer is a, since parallelograms are more general and definitely not rectangles unless specified.
But b (rhombus) is also not a rectangle unless it's a square.
So unless the rhombus has right angles, it's not a rectangle.
But the problem says: “All sides congruent, opposite angles congruent” — that’s a rhombus.
So b is a rhombus, which is not necessarily a rectangle.
So both a and b are not rectangles.
But if c is the only rectangle, then a and b are not.
But the question likely wants one answer.
Perhaps the intended answer is:
✔ a. parallelogram — because it's the most general and clearly not a rectangle.
But better to say: Any of a or b are not rectangles.
But since the packet says “choose one”, probably a.
Alternatively, maybe the question is:
> Which of the following is not a rectangle?
And the figures are:
- a: Parallelogram (not rectangle)
- b: Rhombus (not rectangle)
- c: Square (is rectangle)
So a and b are not rectangles.
But if only one answer is allowed, and c is the only one that is a rectangle, then the answer is a or b.
But perhaps the intended answer is:
✔ a. parallelogram
(Though b is equally valid.)
But let's move on.

#### 1.3. Identifying quadrilaterals from descriptions
> Given: A quadrilateral with two pairs of adjacent congruent sides and diagonals perpendicular, and one diagonal is a line of symmetry.
This is the definition of a kite.
So the answer is:
✔ Kite
---
#### 1.4. Regular vs. Irregular Polygons
> Definition: A regular polygon has all sides and all angles congruent.
> Question: Which of the following is not a regular polygon?
Options:
- a. Equilateral triangle → all sides and angles equal → regular
- b. Rectangle → opposite sides equal, but angles are 90°, but sides not all equal → not regular
- c. Square → all sides and angles equal → regular
- d. Regular hexagon → by name → regular
So only b. rectangle is not regular.
✔ Answer: b. rectangle
---
#### 1.5. Identifying types of triangles
> Given: Triangle with one obtuse angle and two equal sides.
- One obtuse angle → obtuse triangle
- Two equal sides → isosceles triangle
So it is an obtuse isosceles triangle.
✔ Answer: Obtuse isosceles triangle
---
> Task: Use the information to draw a polygon with the following properties:
- 6 sides
- All sides congruent
- All angles congruent
This is a regular hexagon.
So the answer is:
✔ Regular hexagon
You would draw a six-sided polygon with all sides equal and all interior angles equal (each = 120°).
