Angle Relationships
Angles that occur on the same side of the transversal line and are equal in size and are both either acute or obtuse
What are corresponding angles?
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
What is corresponding angles are congruent?
