Question

If two line intersect each other and one angle of vertically opposite angle hair is 125°then what will be measurements of another angle​

Answer 1

Answer:

Given AB and CD are straight lines which intersect at O. OP is the bisector of ∠AO.

To prove: OQ is the bisector of ∠BOD.

Proof: AB, CD and PQ are straight lines which intersect in O.

∠AOP=∠BOQ(vertically opposite angles)

∠COP=∠DOQ(vertically opposite angles)

∠AOP=∠COP(OP is the bisector of ∠AOC)

∴∠BOQ=∠DOQ

Thus, the rate opposite to the bisector of one of the angles thus formed bisects the vertically opposite angle. Similarly, the
