Let's solve the problem step by step.
The task is to
count the number of sides and vertices for each given shape. A
side is a straight line segment that forms part of the boundary of a shape, and a
vertex (plural: vertices) is a corner where two sides meet.
We’ll go through each shape one by one:
---
1.
Triangle
-
Sides: 3 (three straight lines)
-
Vertices: 3 (three corners)
-
✔ Answer: 3 sides, 3 vertices
2.
Square
-
Sides: 4 (all equal in length)
-
Vertices: 4 (four corners)
-
✔ Answer: 4 sides, 4 vertices
3.
Rectangle
-
Sides: 4 (opposite sides are equal)
-
Vertices: 4 (four corners)
-
✔ Answer: 4 sides, 4 vertices
4.
Trapezoid
-
Sides: 4 (one pair of parallel sides)
-
Vertices: 4 (four corners)
-
✔ Answer: 4 sides, 4 vertices
5.
Parallelogram
-
Sides: 4 (two pairs of parallel sides)
-
Vertices: 4 (four corners)
-
✔ Answer: 4 sides, 4 vertices
6.
Pentagon
-
Sides: 5 (five straight sides)
-
Vertices: 5 (five corners)
-
✔ Answer: 5 sides, 5 vertices
7.
Hexagon
-
Sides: 6 (six straight sides)
-
Vertices: 6 (six corners)
-
✔ Answer: 6 sides, 6 vertices

Final Table:
| Shape | Name | Number of Sides | Number of Vertices |
|--------------|--------------|------------------|---------------------|
| 🔺 | Triangle | 3 | 3 |
| 🔵 | Square | 4 | 4 |
| 🔴 | Rectangle | 4 | 4 |
| 🟢 | Trapezoid | 4 | 4 |
| 🔷 | Parallelogram| 4 | 4 |
| 🔴 | Pentagon | 5 | 5 |
| 🟡 | Hexagon | 6 | 6 |

Summary:
For any regular polygon, the number of sides equals the number of vertices. This is true for all the shapes listed here.
✔ Answer Key:
- Triangle: 3 sides, 3 vertices
- Square: 4 sides, 4 vertices
- Rectangle: 4 sides, 4 vertices
- Trapezoid: 4 sides, 4 vertices
- Parallelogram: 4 sides, 4 vertices
- Pentagon: 5 sides, 5 vertices
- Hexagon: 6 sides, 6 vertices
