Question

Can we get sum of any two obtuse angle is a straight angle?why

Answer 1

Answer:

NO.

let A》 90

let B》90

adding above

A+B》 180

so it NOT be straightline any more .since for a straightline angle = 180

Answer 2

No, as any obtuse angle A > π/2 (90°) ...

Proof: Let A and B be 2 obtuse angles...

• A > 90°
• B > 90°

=> A + B > 90° + 90°

Hence, (A + B) > 180°
