Transformations Review - Unit 10

Determine how to translate triangle ABC to triangle A'B'C'.

• (x-2, y+5)
• (x+2, y-9)
• (x-2, y+9)
• (x-9, y+2)

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

Reflect the point (2, -4) over the y-axis.

• (-4, 2)
• (-2, 4)
• (-2, -4)
• (2, 4)

Reflect (6, -3) over the line x-axis.

• (6, 3)
• (-6, -3)
• (-3, 6)
• (3, -6)

The point ( -2,5) is reflected over the line x = 1.  Find its image.

• (  4,  5)
• ( -2  , -5)
• ( 2  ,  5)
• (2   , -5)

Identify the transformation from C to D.

• 90^o Counter Clockwise Rotation
• 180^o Rotation
• 270^o Counter clockwise Rotation
• 360^o Rotation

Identify the transformation from ABC to A'B'C'.

• Reflection across the x-axis
• Reflection across the y-axis
• 90^o clockwise rotation
• 90^o counterclockwise rotation

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down

Write a rule for the translation.

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