Question

2 If one of the four angles formed by two intersecting lines is a right angle, then show
4. In Fig. 10.59, find the value of x.
that each of the four angles is a right angle.​

Answer 1

2} Answer:

Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90°

Now, ∠AOD=∠COB=90 ° (Vertically opposite

angles)

⟹∠AOD+∠DOB=180 ° (Angles on a straight line)

⟹90+∠DOB=180°

∠DOB=90°

∠DOB=∠AOC=90 ° (Vertically opposite angles)

Thus, all angles are 90°
