Interior and Exterior Angles
Interior and Exterior Angles
The two lines IK and JL are parallel. Notice that line GH creates a series of interior and exterior angles.
1. Move point C to a different location.
2. Measure all the interior and exterior angles you create.
3. Record what you notice about the angles.
4. Repeat steps 1-3 two more times.
5. Overall what generalizations can you make about interior and exterior angles created by parallel lines?
