Learning Objective
I can use angle relationships to find missing angle measures.
- 1
When two parallel lines are cut by a transversal, there are relationships between the angles formed, such as alternate interior angles and corresponding angles.
- 2
Supplementary angles form a straight line and their measures add up to 180 degrees.
- 3
Alternate interior angles are congruent, meaning they have the same measure.
