In the figure AB // CD. List 2 pairs of equal corresponding angles and 2 pairs of equal alternate angles.

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) $\angle f = \angle j$

ii) $\angle e = \angle i$ (Other valid pairs: $\angle g = \angle k$, $\angle h = \angle l$, $\angle b = \angle n$, $\angle a = \angle m$, $\angle c = \angle o$, $\angle d = \angle p$)

b) 2 pairs of equal alternate angles.
Alternate angles are on opposite sides of the transversal.

i) $\angle h = \angle i$ (Alternate interior angles)
