Angle Pairs EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.

3
A line that intersects two parallel lines is called a transversal.
EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.

4
Corresponding angles are on the same side of a transversal and are congruent.
EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.

5
Alternate interior angles are on opposite sides of a transversal and are located in between the two parallel lines. Alternate interior angles are congruent. EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.

6
Alternate exterior angles are on opposite sides of a transversal and are on the exterior of the two parallel lines. Alternate exterior angles are congruent. EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.

7
Consecutive interior angles are on the same side of a transversal and are between the two parallel lines. Consecutive interior angles are supplementary which means they add up to 180 degrees. EQ: What are angle pair relationships and what do we know about them? We will write and discuss angle pair relationships.
