Reflect across the x-axis

Reflect across the x-axis Change the sign of the y-value

Reflect across the x-axis

Reflect across the y-axis

Reflect across the y-axis Change the sign of the x-value

Reflect across the y-axis

Reflect across y = x

Reflect across y = x Swap x and y

Reflect across y = x

Reflect across y = -x

Reflect across y = -x Swap and change both signs

Reflect across y = -x

Lines of Symmetry • A line of symmetry is a line you can use to fold a figure so that both halves match up perfectly. This means the figure is symmetrical (balanced/matching) on both sides of the line.

Lines of Symmetry • How many lines of symmetry does the polygon have? 3

Lines of Symmetry • How many lines of symmetry does the shape have? 2

Lines of Symmetry • How many lines of symmetry does the shape have? 5
