Let's solve the problem step by step.
The task is to
draw the lines of symmetry for each shape and write down how many lines of symmetry each shape has.
Here are the shapes shown in the worksheet (from top to bottom, left to right):
---
1. Upward Arrow
- This is a simple arrow pointing up.
- It has
one vertical line of symmetry — if you draw a line down the center, both sides match.
-
Lines of Symmetry: 1
---
2. Oval (Ellipse)
- An oval has
two lines of symmetry:
- One vertical line through the center (top to bottom).
- One horizontal line through the center (side to side).
-
Lines of Symmetry: 2
---
3. Star (Regular 5-pointed star)
- A regular five-pointed star has
five lines of symmetry.
- Each line goes from a point to the midpoint of the opposite side.
-
Lines of Symmetry: 5
---
4. Triangle (Equilateral Triangle)
- Assuming it's an equilateral triangle (all sides equal), it has
three lines of symmetry.
- Each line goes from a vertex to the midpoint of the opposite side.
-
Lines of Symmetry: 3
---
5. Pentagon (Regular Pentagon)
- A regular pentagon has
five lines of symmetry.
- Each line goes from a vertex to the midpoint of the opposite side.
-
Lines of Symmetry: 5
---
6. Diamond (Square rotated 45°)
- This is a square rotated so that its corners face up/down/left/right.
- A square has
four lines of symmetry:
- Two diagonals (from corner to corner).
- One vertical and one horizontal line through the center.
-
Lines of Symmetry: 4

Summary:
| Shape | Lines of Symmetry |
|---------------------|-------------------|
| Upward Arrow | 1 |
| Oval | 2 |
| Star (5-pointed) | 5 |
| Equilateral Triangle| 3 |
| Regular Pentagon | 5 |
| Diamond (Square) | 4 |

How to Draw the Lines of Symmetry:
For each shape:
- Use a ruler to draw straight lines where the shape folds perfectly onto itself.
- For example:
- In the
arrow, draw a vertical line down the middle.
- In the
oval, draw one vertical and one horizontal line through the center.
- In the
star, draw a line from each point to the center of the opposite side.
- In the
triangle, draw a line from each corner to the midpoint of the opposite side.
- In the
pentagon, do the same as the star.
- In the
diamond, draw two diagonals and one vertical and one horizontal line through the center.

✔ Final Answer:
- Arrow: 1
- Oval: 2
- Star: 5
- Triangle: 3
- Pentagon: 5
- Diamond: 4
You can now fill in the worksheet with these numbers and draw the corresponding lines.
