Which set of sides would make a right triangle?

• 4,5,6
• 8,10,12
• 5,12,13
• 5,10,12

Name the transformation.

• Translation
• Reflection
• Rotation

Identify the transformation.

• Reflection across y-axis
• 90 Rotation counter clockwise
• Translation 5 units left, 1 unit up.
• Translation 5 units right, 1 unit down

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

The image shows what type of transformation

• Rotation
• Translation
• Reflection

Is the picture being reflected in the y-axis or x-axis?

• y-axis
• x-axis

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

A(-2, 2) and B(3, 2) 
Dilate k = 2 

• A' (-2, 2), B' (3, 2)
• A' (-4, 4), B' (6, 4)
• A' (2, -2), B' (-3, -2)
• A' (2, -2), B' (2, 3)
