Line of Symmetry | angieb - Free Printable

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

- This is a regular pentagon, which 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, one vertical, and one horizontal.
- Lines of Symmetry: Two diagonals, one vertical, and one horizontal.
- 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 regular star (pentagram), which 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.
- 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
