Angles 3,4,5,8 are interior angles
Angles 1,2,6,7 are exterior angles
Alternate interior angles:
Pairs of interior angles on opposite sides of the transversal.
For instance, angle 3 and angle 5 are alternate interior angles. Angle 4 and angle 8 are also alternate interior angles.
Alternate exterior angles:
Pairs of exterior angles on opposite sides of the transversal.
Angle 2 and angle 7 are alternate exterior angles.
Corresponding angles:
Pairs of angles that are in similar positions.
Angle 3 and angle 2 are corresponding angles.
Angle 5 and angle 7 are corresponding angles
