Question

if 2 lines intersect each other at point o prove that their vertically opposite angles are equal​

Answer 1

Step-by-step explanation:

given; line AB and line CD intersect each other at point O

to prove :angle AOB is congruent to angle COD

Proof:

Angle AOB + angle BOC=180 (angles in linear pair)

angle BOC + angle COD =180(angles in linear pair)

angle AOB +angle BOC =angle BOC + angle COD

BOC and BOC candle each other

therefore,

angle AOB =angle COD

hence proved....

similarly u can prove another side
