Unit Transformation Test

Dilation

• a transformation that enlarges or reduces a figure

• all types of transformation

• when we "flip" across a line of reflection

Image

• a slide or flip

• the original shape or figure

• a shape or figure after a transformation; the new figure

Pre-Image

• a shape or figure after a transformation, the new figure

• a transformation that rotates around the origin

• a shape or figure before a transformation; the original figure

Reflection

• a transformation that produces a mirror image of the original figure over a line of

• a transformation that rotates clockwise or counterclockwise

• when a scale is less than 1

Rotation

• the axis that runs vertical

• a transformation that turns a figure around a center of rotation

• how we calculate the scale factor

Translation

• a transformation that moves each point of a figure the same distance and same direction

• rotation and reflection

• a transformation that moves a figure to no specific location

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis
• y-axis

Identify the transformation.

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

If you were to rotate ABCD 180° about the origin, what would the coordinate of A' be?

• (3, 5)

• (-3, -5)

• (-5, 3)

• (5, 3)

Which way has this F been rotated

• Up

• Across

• Clockwise

• Anit-clockwise
