1. 8.2: Similar Polygons Objective: To identify and apply similar polygons

2. Similar Polygons (~)  Same shape but not necessarily the same size Two Polygons are similar if: 1.Corresponding angles are congruent 2.Corresponding sides are proportional Similarity Ratio: ratio of the corresponding sides of similar figures

3. Determining Similarity and Writing Similarity Ratios corresponds to:  Corresponding Angles are congruent Similarity ratio:Similarity statement: A F B C E D 15 12 18 20 24 16

4. ABCD ~ EFGH (this is called a similarity statement) A BC DE F G H 53° 127°6 8 6 8 3 3 4 4 Find the following: 1.m E3. 2.m B 4. Similarity Ratio=
