UNIT 3- RIGID MOTION VOCABULAR

What is the definition of a transformation?

• The action of taking a figure and moving it to a different location without altering its shape or size

• An operation that maps an original geometric figure onto a new figure

• A function that moves every point a constant distance in a specified direction

• A congruence transformation that turns a figure about a fixed point

Which term describes the action of taking a figure and moving it to a different location without altering its shape or size?
