This document defines key terms related to translations in the coordinate plane, including that a coordinate plane is divided into four quadrants by the x-axis and y-axis, and that a translation slides every point of a figure the same distance in the same direction while maintaining the original shape. Examples of coordinate planes showing the four quadrants are provided for illustration.
