What are dilations, similarity and scale factors

The video tutorial introduces the concept of dilations, a type of transformation that changes the size and shape of a figure. It contrasts dilations with previous transformations like reflections, translations, and rotations, which maintain the original size and shape. The tutorial explains how dilations can enlarge or reduce a figure using scale factors, with practical examples using triangles to illustrate these concepts.

What does it mean for figures to be similar in the context of dilations?

Describe the process of creating a dilation from a fixed point.

How can you identify the original shape when performing transformations?
