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.
