The student will be able to:

1. Identify similar polygons.
2. Identify corresponding parts of similar polygons.
3. Apply proportions to problems using similar figures and scale drawings.
4. Prove triangles similar using AA, SAS, SSS Similarity Theorems.
5. State and apply the relationship between parallel lines and proportional segments in triangles.
6. Solve simple algebraic equations.
