Students identify and draw lines of symmetry for various geometric shapes on this educational worksheet.

To solve the problem of identifying and drawing the lines of symmetry for each shape, we need to determine how many lines of symmetry each shape has. A line of symmetry is a line that divides a shape into two identical halves that are mirror images of each other.

Let's analyze each shape step by step:

Shape A: Rectangle

- A rectangle has 2 lines of symmetry: one vertical and one horizontal.
- Lines of Symmetry: Vertical and Horizontal
- Number of Lines: 2

Shape B: Triangle

- This is an equilateral triangle, which has 3 lines of symmetry: one through each vertex and the midpoint of the opposite side.
- Lines of Symmetry: Three lines from each vertex to the midpoint of the opposite side.
- Number of Lines: 3

Shape C: Arrow

- The arrow has 1 line of symmetry: vertical.
- Lines of Symmetry: Vertical
- Number of Lines: 1

Shape D: Pentagon

- A regular pentagon has 5 lines of symmetry: one through each vertex and the midpoint of the opposite side.
- Lines of Symmetry: Five lines from each vertex to the midpoint of the opposite side.
- Number of Lines: 5

Shape E: Square

- A square has 4 lines of symmetry: two diagonals and two lines through the midpoints of opposite sides.
- Lines of Symmetry: Two vertical/horizontal and two diagonal.
- Number of Lines: 4

Shape F: Heart

- The heart shape has 1 line of symmetry: vertical.
- Lines of Symmetry: Vertical
- Number of Lines: 1

Shape G: Star

- This is a five-pointed star (regular pentagram). It has 5 lines of symmetry: one through each point and the midpoint of the opposite side.
- Lines of Symmetry: Five lines from each point to the midpoint of the opposite side.
- Number of Lines: 5

Shape H: Crescent Moon

- The crescent moon shape does not have any lines of symmetry because it cannot be divided into two identical halves.
- Lines of Symmetry: None
- Number of Lines: 0

Shape I: Double Arrow

- The double arrow has 1 line of symmetry: vertical.
- Lines of Symmetry: Vertical
- Number of Lines: 1

Final Answer Summary:

- A: 2 lines
- B: 3 lines
- C: 1 line
- D: 5 lines
- E: 4 lines
- F: 1 line
- G: 5 lines
- H: 0 lines
- I: 1 line
