Answer:
Given, two straight lines intersect each other in such a way that one of the angles formed measure 90°.
We know that, lines which intersect to form a right angle are known as perpendicular lines
In the above figure , AB is perpendicular to CD
Considering ∠AOC=90°
Now,
∠AOC+∠AOD=180° [Linear pair]
90°+∠AOD=180°
∠AOD=90°
Similarly,
∠AOC+∠BOC=180° and ∠BOD+∠AOD=180° [Both making linear pair]
So, we get ∠BOC=90° and ∠BOD=90°
Hence, ∠AOC=∠AOD=∠BOC=∠BOD=90°
