The image you've uploaded is a
symmetry worksheet titled "Symmetry," designed to help students practice identifying and completing shapes based on a line of symmetry. The task involves
completing each drawing so that the dotted line is the line of symmetry.

🔍 Understanding the Task
A
line of symmetry divides a shape into two mirror-image halves. If you fold the shape along this line, both sides should match perfectly.
In this worksheet:
- Each shape has a
dotted line indicating the line of symmetry.
- One side of the shape is already drawn.
- You must
draw the missing half to make the shape symmetrical across the dotted line.
---
✔ How to Solve It Step-by-Step
For each shape:
1.
Identify the line of symmetry (the dotted line).
2.
Look at the existing part of the shape.
3.
Reflect each point or edge across the dotted line.
4.
Draw the mirrored half so that it matches the original side exactly.
---
🧩 Example: First Shape (Top Left)
- Shape: A triangle with a curved edge on the right.
- Dotted line: Vertical line through the middle.
- To complete:
- Reflect the curved edge and straight edges across the dotted line.
- Draw the left side as a mirror image of the right side.
> This results in a
symmetrical shape where both sides are identical when folded along the dotted line.

📐 General Tips for Completing the Shapes
- Use a ruler to ensure straight lines.
- Pay attention to
corners, curves, and angles—they must be mirrored accurately.
- Imagine folding the paper along the dotted line; the drawn side should match the blank side.

✔ Final Answer (Summary)
To solve the worksheet:
>
For each shape, draw the missing half so that it is a mirror image of the given half across the dotted line (the line of symmetry).
This ensures the entire shape is symmetrical.

Since I can't draw directly here, I’ll describe how to complete each shape if you're doing it by hand:
| Row | Shape Description | How to Complete |
|-----|-------------------|-----------------|
| 1 | Quarter circle with arc on right | Draw matching arc on left |
| 2 | Right triangle with hypotenuse on right | Mirror the triangle to the left |
| 3 | Irregular shape with zigzag edge | Reflect zigzag across dotted line |
| 4 | Trapezoid with slanted top | Draw mirror trapezoid on other side |
| 5 | L-shaped figure | Reflect the "L" across the line |
| 6 | Arrow-like shape | Draw the opposite arrowhead |
| 7 | Rectangle with cut-out | Mirror the cut-out |
| 8 | Hexagon with one side missing | Complete the symmetric side |

🎯 Key Concept
>
Symmetry means balance: Every point on one side has a corresponding point on the other side, equidistant from the line of symmetry.
