Here are the solutions to the problems:
Q1: In the figure AB // CD. List,
a) 2 pairs of equal corresponding angles.
Corresponding angles are in the same relative position at each intersection.
i) ∠f=∠j
ii) ∠e=∠i (Other valid pairs: ∠g=∠k, ∠h=∠l, ∠b=∠n, ∠a=∠m, ∠c=∠o, ∠d=∠p)
b) 2 pairs of equal alternate angles.
Alternate angles are on opposite sides of the transversal.
i) ∠h=∠i (Alternate interior angles)
