(a) In the diagram provided, the alternate interior angles are
Angle 3 and angle 5
Angle 4 and angle 6
(b) Angle 4 and angle 8 are corresponding angles. Corresponding angles are equal. Therefore, angle 4 is equal to angle 8
(c) Angle 4 and angle 5 are same side interior angles
Angle 3 and angle 6 are same side interior angles
