Let's solve the
"Lines of Symmetry" worksheet step by step.

🔍 Understanding the Task
We are given 6 shapes on the left and a list of numbers (4, 3, 2, 1) on the right.
For each shape:
- Identify how many
lines of symmetry it has.
- Draw a line from the shape to the correct number that matches the number of symmetry lines.
---
✔ Step-by-Step Analysis of Each Shape
#### 1.
Square
- A square has
4 lines of symmetry:
- 2 diagonals
- 1 vertical line through the middle
- 1 horizontal line through the middle
✔ → Connect to
4
#### 2.
Equilateral Triangle
- An equilateral triangle has
3 lines of symmetry:
- One from each vertex to the midpoint of the opposite side
✔ → Connect to
3
#### 3.
Heart
- A heart typically has
1 line of symmetry:
- Vertical line down the center (left and right sides match)
✔ → Connect to
1
#### 4.
Isosceles Trapezoid
- This trapezoid has
1 line of symmetry:
- Vertical line through the midpoints of the two parallel sides
✔ → Connect to
1
#### 5.
Rectangle
- A rectangle has
2 lines of symmetry:
- 1 vertical (through the middle)
- 1 horizontal (through the middle)
- Note: Diagonals are
not lines of symmetry in a rectangle.
✔ → Connect to
2
#### 6.
Diamond (Rhombus)
- A rhombus has
2 lines of symmetry:
- The two diagonals (they split the rhombus into symmetrical halves)
✔ → Connect to
2

📌 Final Matching:
| Shape | Lines of Symmetry | Match to |
|-----------------|-------------------|----------|
| Square | 4 | 4 |
| Triangle | 3 | 3 |
| Heart | 1 | 1 |
| Trapezoid | 1 | 1 |
| Rectangle | 2 | 2 |
| Diamond (Rhombus)| 2 | 2 |

✔ Answer Summary:
-
Square → 4
-
Triangle → 3
-
Heart → 1
-
Trapezoid → 1
-
Rectangle → 2
-
Diamond → 2
> 💡 Note: The numbers on the right are listed as: 4, 3, 2, 1, 2, 1 — so you can draw lines from each shape to its matching number.

🖋️ How to Complete the Worksheet:
1. For each shape, draw the actual
lines of symmetry inside the shape.
2. Then, draw a
line connecting each shape to the correct number on the right.
