Translation + Reflection

How is triangle ABC being translated to triangle A'B'C'?

• up 3, left 8

• up 9, left 4

• down 3, right 8

• down 9, right 4

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3

• slide right 2, up 3

• slide right 2, down 3

• slide left 3, right 2

Write the rule for this translation:
Slide 3 up and 2 right

• (x, y)---->(x + 3, y + 2)

• (x, y)-----> (x+2, y + 3)

• (x, y)----> (x - 2, y + 3)

What axis is the triangle being reflected over?

• X-axis

• Y-axis

What axis is the image reflected over?

• X-axis

• Y-axis

Reflect Point C over the y-axis:

• (-3, 2)

• (3,2)

• (-2,3)

• (3,0)

Reflect over x-axis. Which point would be at (3, -6)

• A

• B

• C

• H

Select ALL correct ordered pairs after a reflection across the x axis.

• K' (1 , 1)

• K' (-1,-1)

• N' (4 , 0)

• N' (-4 , 0)

• Q' ( 4 , 4)

Which rule would give the translation from point P (2, 5) to the image P′ (−1, 7)?

• Move 3 units left and 2 units up.

• Move 3 units right and 2 units up.

• Move 3 units left and 7 units up.

• Move 2 units right and 2 units up.

Point R′ (−2, 8) is the image of point R (−2, 2). Which of the following could be that transformation?

• A reflection across the y-axis

• A dilation with a scale factor of 4

• A translation of 6 units up

• A translation of 6 units to the right
