Let's solve the worksheet step by step.
We are asked to identify the
number of sides and
corners (vertices) for each 2D shape shown.
---
1. Square
- A square has
4 equal sides.
- It also has
4 corners (each corner is a right angle).
✔ Answer:
- Number of sides:
4
- Number of corners:
4
---
2. Triangle
- A triangle has
3 sides.
- It has
3 corners (also called vertices).
✔ Answer:
- Number of sides:
3
- Number of corners:
3

3. Pentagon
- A pentagon has
5 sides.
- It has
5 corners.
✔ Answer:
- Number of sides:
5
- Number of corners:
5
---
4. Rectangle
- A rectangle has
4 sides (opposite sides are equal).
- It has
4 corners (all right angles).
✔ Answer:
- Number of sides:
4
- Number of corners:
4
---

💡
Note: In 2D shapes, the number of
sides is always equal to the number of
corners (vertices). This is true for all polygons.
✔ So, fill in the blanks as follows:
```
Square:
[4] sides
[4] corners
Triangle:
[3] sides
[3] corners
Pentagon:
[5] sides
[5] corners
Rectangle:
[4] sides
[4] corners
```
