EVERY POINT on the figure
undergoes the SAME transformation
Description = a verbal expression
Describe each translation using words like units, up, down, left, and right.

Important Aspects of a Translation:1. A translation occurs when a figure slides across a coordinate plane.
2. If a figure is translated horizontally (left or right) the x coordinate changes.
3. If a figure is translated vertically (up or down) the y coordinate changes.
4. A translated figure will never change in size or shape but only in its location.
