This document defines and describes four types of angles formed when two lines are cut by a third line called a transversal: same-side interior angles are on the same side of the transversal, alternate exterior angles are nonadjacent exterior angles on opposite sides, alternate interior angles are nonadjacent interior angles on opposite sides, and corresponding angles are on the same side of the transversal in corresponding positions.

1. Lines and Angles

2. Goal 1:
Identify same-side interior,
alternate exterior, alternate interior,
and corresponding angles

3. Same-side Interior
interior angles that are
on the same side of the
transversal.

4. Alternate Exterior
nonadjacent exterior angles
that lie on the opposite sides of
the transversal.

5. Alternate Interior
nonadjacent interior angles
that lie on opposite sides of the
transversal.

6. Corresponding Angles
lie on the same side of the
transversal and in
corresponding positions.

Packet.
