Question

If one of the four angles formed by two intersecting lines is a right angle, then show
that each of the four angles is a right angle.​

Answer 1

One angle = 90 degree

Opposite angle= 90 degree[Vertically opposite angles]

Each adjacent angle= 180 - 90 = 90 degree[Linear pairs]

Hence all the four angles are right angles
