Translation (Slide)

A transformation that "slides" each point of a figure the same distance in the same direction.

The act of sliding a figure in any direction.

What are the new points??

Reflection (flip)

• A transformation that "flips" a figure over a line of reflection.

Click on this trapezoid to see reflection.

The result of a figure flipped over a line.
