Identifying Similarity

by:caylin buffington

Definition

Two figures are similar if the second can be obtained from the first by a sequence of transformations and dilation.

Dilation

Dilation is when one shape expands or gets bigger.



How to check similarity

1. Count each shapes sides down then right.

2.Write ratios comparing the lengths of each side.

3. Simplify the fractions and compare each fraction to another.

4. If the fractions are all equal then they are similar, if not then they aren't.
