Review your work on the Self Check problem and think about these questions:

- What are the sums of the angle measures in different polygons?
- How can you find the measure of ∠
*FGE*? - What angle does ∠
*BGC*and ∠*CGE*form? - What do you know about the angles formed by two intersecting lines?
- Find a different way of solving the problem.
- What do you know about the angles in parallelograms, triangles, and other polygons?
