Question

To prove that the opposite angles formed
by two interseating lines are of equal

measures​

Answer 1

Answer:

Example ⇒∠AOC=∠BOD. we can see that the angles ∠AOC and ∠BOD are vertically opposite angles. So, we have proved that if two lines intersect each other, then the vertically opposite angles are equal.

Answer 2

Answer:

To prove vertically opposite angles are equal , you have to done this with linear pair concept

Step-by-step explanation:

Take two lines AB and PQ both intersect at O

now

Angle AOQ+ BOQ = 180 -------- 1

Similarly

Angle BOQ + angle POB = 180° --------2

From equation 1 and 2 we get

Angle AOQ = POB
