After any of these transformations (turn around, flip or slide), the shape still has the same size, area, angles and line lengths.  In all these transformations congruence is preserved.

Congruent or Similar

Two shapes are Similar if you need to Resize for one shape to become another (you may also Turn, Flip and/or Slide).

Dilation

The other important Transformation is Dilation (also called reduction or enlargement). The new image becomes bigger or smaller.
