Answer: Dilation and stretch
Step-by-step explanation:
- Rigid transformations that are also called as isometry are the transformations which preserves the side lengths and the angle measures of a polygon. It does not affect the size of the shape. The shape doesn't shrink or get enlarger.
There are four rigid transformations: reflections, rotations, translations and glide reflection.
- Dilation and stretch are non rigid transformation because they change the size of the figure. They produces similar figures.
