Translation

HSG-CO.A.5

Definition

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

Examples

  • Sliding triangle ABC to triangle A'B'C' without turning or flipping it is a translation.
  • Moving a figure 3 units right and 2 units up is a translation.

Key rule

A translation keeps the figure's size, shape, and orientation the same.

Memory hook

Slide it — same size, same direction, no turning.
