Translation (Homework & Handout)

A translation moves every point of a figure the same ​ (a)   and the same ​ (b)  

• direction
• distance.
• clockwise
• counterclockwise
• flip
• rotates

A translation can move a figure a figure ​ (a)   and ​ (b)  

• left/right
• up/down
• clockwise
• counterclockwise

Translations are also thought of as

• Flip and Mirror Image

• Rotate

• Slide

• Enlarge and Reduce

Answer explanation

An image is notated with an apostrophe.

A', B' C' etc.

verbally stated as "prime"

Which graph(s) show a translation left and up?

• Graph A

• Graph B

• Graph C

Which translation(s) preserved orientation of the figure and its vertices?

• Graph A

• Graph B

• Graph C

Answer explanation

Translation preserves:

Orientation of figure - direction of shape

Orientation of Vertices - order
