3-2 geometry
alternate interior angles
The pairs of angles on opposite sides of the transversal but inside the two lines
alternate exterior angles
The pairs of angles on opposite sides of the transversal but outside the two lines are called alternate exterior angles
corresponding angles
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.
same side interior angles
the pair of angles on the same side of the transversal, but inside the 2 parallels lines are called same side interior angles
same side exterior angles
the pair of angles on the same side of the transversal, but outside of the parallel lines are called same side exterior angles.
