I can solve a proportion
I can use given information to establish corresponding parts of similar triangles using congruent angles and proportional sides.
I can fill in missing statements and reasons for a partially completed two-column proof about similar triangles.
There are three sections to this assignment. The first two practice simple and linear proportions.
The last section, Quadratic Proportions, will help you get ahead for next year.
