Question

Atmost how many obtuse angle(s) can we have in a triangle?

• A. 3
• B. 2
• C. 0
• D. 1

Answer 1

The correct option is D 1

Obtuse angle is an angle whose measure is greater than ${90}^{\circ }$.
If there are two obtuse angles in a triangle, then the sum of all angles will become more than ${180}^{\circ }$ and it violates angle sum property.

So, we can have atmost one obtuse angle in a triangle.
