Two figures are similar if they have the same shape, or if one has the same shape as the mirror image of the other. This video explains how it works.

Two figures are similar if they both have the same shape. If A and B are two similar figures, this is expressed as

The factor a similar figure has been scaled up or down by. The scale factor is a number larger than 1 in the case of a scale-up, and a number between 0 and 1 in the case of a scale-down.

Two geometric objects are said to be congruent if they have the same shape and size. If A and B are two congruent objects, it's expressed as

A polygon made up of three edges and three vertices
