sed on Practice Set 2.2
Prove that the bisector of a pair of interior angles formed on the same side of the transversal are
perpendicular.​

Answer 1

Do u mean sum???if it is that then,

We know that the sum of interior angles on the same side of the transversal is 180° then if they bisect means it becomes half of 180° i.e,90° which means perpendicular

Hope it helps
