Question

From this diagram, select the

pair of lines that must be
parallel if 24 = 23. If there
is no pair of lines, select
"none."

Answer 1

O is parallel to q

let's take the angle opposite to angle 4 is alpha

angle 4 = angle alpha ( vertically opposite angles)

angle alpha = angle 3 ( as angle 4 = angle 3).

hence o is parallel to q as both the angles are equal
