Question

The figure below shows a transversal t which intersects the parallel lines PQ and RS.

Write a paragraph to prove that the measure of angle 3 is equal to the measure of angle 5.

Answer 1

line t is a transversal crosses two parallel lines. angle 3 and angle 5 are inside the parallel lines, and on opposite sides of the transversal therefore they are equal
xD

Answer 2

or angles 3 and 5 are alternate interior angles which makes them equal
