Question

in fig it is being given that angle 1 = 65° find all other angle​

Answer 1

If 1 = 65⁰

Then, 3 = 65⁰ ... vertically opposite angle.

Also 2 and 4 = 115⁰ ... By linear pair axiom.

Answer 2

1 = 3 = 65° [Opposite angles]

2 + 3 = 180° [Supplementary angles]

2 = 180° - 65°

2 = 115°

2 = 4 = 115° [Opposite angles]
