# 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. **
