Reflections 30 Reflect across y=x (x,y)  (y,x) Reflect across x-axis (x,y)  (x,-y) Reflect across y-axis (x,y)  (-x,y) Reflect across y=x Reflect across x-axis Reflect across y-axis Reset Figure We want to do one of these reflections

Reflect across y-axis (1,2)  (-1,2) (2,2)  (-2,2) (2,4)  (-2,4) Problem Name Reflect across y=x (-1,2)  (2,-1) (-2,2)  (2,-2) (-2,4)  (4,-2) Reflect the following triangle across y-axis and across y=x

1. The square to the right is to be reflected about the y=x and then reflected about the x-axis. Which one below would be the result of these reflections? Problem Name A)B) C) D)

2. The triangle to the right is be translated 4 units to the right and then reflected about the x-axis. Which choice below would result from this translation and reflection? Problem Name A)B) C) D)

3. The trapezoid to the right is to be rotated 180 from the original position. Which choice below would represent this rotation? Problem Name A)B) C)D)

4. The pentagon to the right is to be translated down 5 units down across the x-axis and then translated to the left 5 units across the y-axis. Which of the following would be the best result? Problem Name A) B) C) D)

5. The triangle to the right is to be reflected across y= -x. Which choice below is the correct reflection? Problem Name A) B) C) D)

6.The triangle to the right is to be translated 7 units to the right across the y-axis and then reflected about the x-axis. Which of the following would represent this translation and reflection? Problem Name A)B) C)D)

7. The rectangle to the right is to be reflected across y=4. Which choice below displays this reflection? Problem Name A) B) C)D)
