Warm up Translate (x – 9, y + 8) • B (-9, 12) • A (-12, -4) • T (22, -19) B’ (-18, 20) A’ (-21, 4) T’ (13, -11)
You can do this. It’s time for another skills check. Don’t be scared.
Reflect across the x-axis Change the sign of the y-value
Reflect across the y-axis Change the sign of the x-value
Reflect across y = x Swap x and y
Reflect across y = -x Swap and change both signs
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
