Question

- Two lines AB and CD intersect each other at point O. If line OP bisects angle BOD, prove
that if OP is produced backwards then it bisects angle AOC.
​

Answer 1

Step-by-step explanation:

we know that Vertically Opposite Angles are the angles opposite each other when two lines cross and vertically opposite angles are equal:

so when op bisect angleBOD

so angle BOP =angle POD

THAT IS 1=2

SO if we extend op then it will also bisect COA
