This worksheet challenges students to identify and draw the lines of symmetry for sixteen different geometric shapes and symbols.

To solve the problem of identifying and drawing the lines of symmetry on these shapes, we need to determine where a shape can be folded such that both halves match perfectly. Here's a step-by-step explanation for each shape:

---

Row 1:

1. Square (Rectangle):
- A square has 4 lines of symmetry: two vertical, two horizontal.
- Draw one vertical line through the center, one horizontal line through the center, and two diagonal lines from corner to corner.

2. Heart:
- A heart has 1 line of symmetry: vertical.
- Draw a vertical line down the middle.

3. Cross with Arrows:
- This shape has 4 lines of symmetry: two vertical, two horizontal.
- Draw one vertical line through the center, one horizontal line through the center, and two diagonal lines from corner to corner.

4. Trapezoid:
- A trapezoid with equal non-parallel sides has 1 line of symmetry: vertical.
- Draw a vertical line down the middle.

Row 2:

5. Parallelogram:
- A generic parallelogram has 0 lines of symmetry unless it is a special case like a rectangle or rhombus.
- No lines of symmetry.

6. Arrow (Pointing Up):
- This arrow has 1 line of symmetry: vertical.
- Draw a vertical line down the middle.

7. L-shaped Figure:
- This shape has 1 line of symmetry: vertical.
- Draw a vertical line down the middle.

8. Irregular Pentagon:
- This irregular pentagon has 0 lines of symmetry.
- No lines of symmetry.

Row 3:

9. Curved Arrow:
- This shape has 0 lines of symmetry.
- No lines of symmetry.

10. Wavy Line:
- This shape has 0 lines of symmetry.
- No lines of symmetry.

11. Pentagon:
- A regular pentagon has 5 lines of symmetry.
- Draw 5 lines connecting each vertex to the midpoint of the opposite side.

12. Diamond (Rhombus):
- A diamond has 4 lines of symmetry: two vertical, two horizontal.
- Draw one vertical line through the center, one horizontal line through the center, and two diagonal lines from corner to corner.

Row 4:

13. Star:
- A regular star (pentagram) has 5 lines of symmetry.
- Draw 5 lines connecting each point to the midpoint of the opposite side.

14. Hexagon:
- A regular hexagon has 6 lines of symmetry: three vertical, three horizontal.
- Draw three vertical lines, three horizontal lines, and three diagonal lines.

15. Square with Rounded Corners:
- This shape has 4 lines of symmetry: two vertical, two horizontal.
- Draw one vertical line through the center, one horizontal line through the center, and two diagonal lines from corner to corner.

16. Plus Sign (+):
- This shape has 4 lines of symmetry: two vertical, two horizontal.
- Draw one vertical line through the center, one horizontal line through the center, and two diagonal lines from corner to corner.
