Let's solve the problem step by step.
We are given a worksheet titled
"Identify 2D Shapes Sheet 3", where we need to:
1. Count the number of
sides and
corners (vertices) for each shape.
2. Write the
name of the shape.
There are six shapes shown in the grid, and we'll analyze each one.
---
🔹 Shape 1: First shape (top-left)
- It is a
square.
-
Sides: 4
-
Corners: 4
-
Name of shape: Square
✔ This matches the definition: all sides equal, all angles 90°.
---
🔹 Shape 2: Second shape (top-center)
- It is a
rectangle.
-
Sides: 4
-
Corners: 4
-
Name of shape: Rectangle
✔ Opposite sides are equal, all angles are 90°.
---
🔹 Shape 3: Third shape (top-right)
- It is an
isosceles triangle (two equal sides).
-
Sides: 3
-
Corners: 3
-
Name of shape: Isosceles Triangle
✔ Two sides are equal; two angles are equal.
---
🔹 Shape 4: Fourth shape (bottom-left)
- It is a
parallelogram.
-
Sides: 4
-
Corners: 4
-
Name of shape: Parallelogram
✔ Opposite sides are parallel and equal.
---
🔹 Shape 5: Fifth shape (bottom-center)
- It is a
scalene triangle (all sides different).
-
Sides: 3
-
Corners: 3
-
Name of shape: Scalene Triangle
✔ All three sides have different lengths.
---
🔹 Shape 6: Sixth shape (bottom-right)
- It is a
rectangle (same as shape 2).
-
Sides: 4
-
Corners: 4
-
Name of shape: Rectangle
✔ Again, opposite sides equal, all angles 90°.

✔ Final Answers:
| Shape | Sides | Corners | Name of Shape |
|------|-------|--------|----------------|
| 1 (Square) | 4 | 4 | Square |
| 2 (Rectangle) | 4 | 4 | Rectangle |
| 3 (Triangle) | 3 | 3 | Isosceles Triangle |
| 4 (Parallelogram) | 4 | 4 | Parallelogram |
| 5 (Triangle) | 3 | 3 | Scalene Triangle |
| 6 (Rectangle) | 4 | 4 | Rectangle |

📝 Notes:
- The word bank at the bottom includes:
- Rectangle
- Scalene Triangle
- Parallelogram
- Square
- Isosceles triangle
- Rectangle (repeated)
So, you can use these to match the correct names.
