1. Geometry Section 3.1 Transversals & Related Angles

2. A transversal is a line which intersects two coplanar lines at different points. In the figure below, line ____ is a transversal.

3. When you have a transversal, there are four types of special pairs of angles that are formed.

4. Corresponding angles are two angles in the same position relative to the two lines and the transversal.

5. Same-side interior angles are two angles on the same side of the transversal and between the two lines.

6. Alternate interior angles are two angles on opposite sides of the transversal and between the two lines.

7. Alternate exterior angles are two angles on opposite sides of the transversal and outside the two lines.

8. Examples: For each pair of angles, identify the transversal and the two lines that form the pair of angles and classify each pair of angles as one of the types above or write “none”.
