01 / QUICK RECAP
Connect the ideas.
- An angle measures a turn, not the length of its arms.
- Angles on a straight line total 180 degrees; angles around a point total 360 degrees.
- Vertically opposite angles are equal. Parallel lines give corresponding and alternate equal angles, while co-interior angles sum to 180 degrees.
- The interior angles of a triangle total 180 degrees; a simple n-sided polygon has total (n−2)×180 degrees.
- Classify a shape by properties that must be true, and put more specific categories first in a sorting algorithm.
