How do I know if the shape is Congruent or Similar?
If one shape can become another using only Turns, Flips and/or Slides, then the two shapes are called Congruent.
Two shapes are Similar if you need to Resize for one shape to become another (you may also Turn, Flip and/or Slide).
After these transformations (turn around/rotation, flip/reflection or slide/translation ), the shape still has the same size, area, angles and line lengths. This means that in these 3 transformations congruence is preserved.
Dilation –> Enlarge/Grow or Reduce/Shrink
The other important Transformation is Dilation (also called reduction or enlargement). The new image becomes bigger or smaller than the original.
