When a transversal crosses a pair of parallel lines same side interior bond angle pair are supplimentary.
What is bond angle?
bond angle is the space between two intersecting lines or surface at or close to the point where they meet.
Sol-We are given that two parallel lines are intersected by a transversal.
We have to find pair of supplementary angles.
Supplementary angle: Two angles whose sum is equal to 180 degrees are called supplementary angles.
Corresponding angles
It is not necessary that sum of corresponding bond angle is always equal to 180 degrees.Therefore, pair of angles are not always supplementary.
Thus it is true.
