## Topic 19 - Transformations, Congruence, and Symmetry

## TransformationsIf one shape can become another using Turns, Flips and/or Slides, then the two shapes are called congruent.
Congruent: After any of those transformations (turn, flip or slide), the shape still has the same size, area, angles and line lengths. ## ResizingThe other important Transformation is
Resizing (also called dilation, contraction, compression, enlargement or even expansion). The shape becomes bigger or smaller: Source: classroommagic.blogspot.com via Leslie Marrie Scroggs on Pinterest |
