Step-by-step solution for: Identifying Quadrilateral worksheet
Let's solve this step by step. We are given 12 quadrilaterals (four-sided shapes), and we need to identify each one using the correct name from the list:
Possible names:
- rhombus
- quadrilateral (a general term for any four-sided shape)
- rectangle
- square
- trapezoid
- parallelogram
We’ll go through each shape and analyze its properties.
---
- Quadrilateral: Any four-sided polygon.
- Trapezoid: At least one pair of parallel sides.
- Parallelogram: Two pairs of parallel sides.
- Rectangle: A parallelogram with four right angles.
- Rhombus: A parallelogram with all four sides equal.
- Square: A rectangle with all sides equal (or a rhombus with right angles).
---
Now let’s examine each shape:
---
1)
- Shape: A rectangle (has four right angles, opposite sides equal and parallel).
- ✔ Answer: rectangle
---
2)
- Shape: One pair of parallel sides (top and bottom), not the other pair.
- This is a trapezoid.
- ✔ Answer: trapezoid
---
3)
- Shape: All angles appear to be right angles, and it looks like a rectangle rotated.
- Opposite sides are equal and parallel, and angles are 90°.
- ✔ Answer: rectangle
---
4)
- Shape: Looks like a square, but tilted. All sides seem equal, and angles are 90°.
- So it's a square.
- ✔ Answer: square
---
5)
- Shape: Only one pair of sides appears parallel (top and bottom). The other two sides are slanted.
- This is a trapezoid.
- ✔ Answer: trapezoid
---
6)
- Shape: All sides look equal in length, and it's a diamond shape.
- It has two pairs of parallel sides → parallelogram.
- But all sides equal → rhombus.
- ✔ Answer: rhombus
---
7)
- Shape: Two pairs of parallel sides, but angles are not right angles.
- Sides are not necessarily equal — just opposite sides are equal and parallel.
- This is a parallelogram.
- ✔ Answer: parallelogram
---
8)
- Shape: A perfect square (all sides equal, all angles 90°).
- So it's both a square, rectangle, rhombus, parallelogram, and quadrilateral.
- But we choose the most specific name: square.
- ✔ Answer: square
---
9)
- Shape: Two pairs of parallel sides, but angles are not 90°, and sides are unequal.
- This is a parallelogram.
- ✔ Answer: parallelogram
---
10)
- Shape: Only one pair of parallel sides (left and right? Actually, top and bottom may be parallel? Wait — looks like only one pair is parallel).
- Actually, looking closely: the left side is vertical, the right side is slanted — so only one pair of parallel sides (top and bottom).
- So this is a trapezoid.
- ✔ Answer: trapezoid
---
11)
- Shape: Two pairs of parallel sides, but angles are not 90°, and sides are not all equal.
- Opposite sides are equal and parallel → parallelogram.
- ✔ Answer: parallelogram
---
12)
- Shape: Looks like a rectangle that's been rotated.
- All angles are 90°, opposite sides equal and parallel.
- So it's a rectangle.
- ✔ Answer: rectangle
---
1) rectangle
2) trapezoid
3) rectangle
4) square
5) trapezoid
6) rhombus
7) parallelogram
8) square
9) parallelogram
10) trapezoid
11) parallelogram
12) rectangle
