TRANSFORAMTIONS

There are 4 types of TRANSFORMATIONS that we will be learning about.Click here to view information on all 4 transformations (translations, reflections, rotations, and dilations) or click here to play a video that explain each transformation.

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.
