Let's analyze the shapes in the image and determine the number of lines of symmetry for each:

1. **Shape 1 (A semicircle with a straight edge)**:
   - This shape has **1 line of symmetry**, which is the vertical line that divides the semicircle into two equal halves.

2. **Shape 2 (A square)**:
   - A square has **4 lines of symmetry**. These include two diagonals and two lines through the midpoints of opposite sides (vertical and horizontal).

3. **Shape 3 (A star)**:
   - Assuming the star is regular (meaning all arms are equal in length), it has **4 lines of symmetry**. Each line passes through opposite tips or through the midpoints of opposite arms.

4. **Shape 4 (A trapezoid)**:
   - This trapezoid, being an isosceles trapezoid (with equal-length non-parallel sides), has **1 line of symmetry**, which is the vertical line passing through the midpoint of the top and bottom bases.

5. **Shape 5 (A circle)**:
   - A circle has **infinite lines of symmetry** because any diameter drawn through the center divides the circle into two equal halves.

### Recap:
1. Shape 1: 1 line of symmetry.
2. Shape 2: 4 lines of symmetry.
3. Shape 3: 4 lines of symmetry.
4. Shape 4: 1 line of symmetry.
5. Shape 5: Infinite lines of symmetry.

Would you like further details on any of these shapes or how symmetry works?

Here are 5 questions to deepen your understanding:
1. How would the number of symmetry lines change if the star in shape 3 had unequal arms?
2. Can a square have more than 4 lines of symmetry? Why or why not?
3. What other types of trapezoids could exist, and how would their symmetry differ?
4. Why does a circle have infinite lines of symmetry, but a square has only 4?
5. How does rotational symmetry differ from line symmetry, and which shapes here have both?

**Tip**: In any regular polygon (e.g., a square or equilateral triangle), the number of lines of symmetry is equal to the number of sides!
