Lesson 11: Polygons and Quadrilaterals Unit Review

Sample Work

Step 2 - Identify which formula we use to prove certain properties of polygons.

Below are properties of triangles/quadrilaterals you’ve been working with closely. Look at the properties given, then match it with the formula you would use to prove it. (Hint: think about the type of answers we expect from each of the formulas listed - use your answers from Step 1 to help!)
