True or False? In an obtuse triangle all the angles are obtuse. I think it's false but I'm not sure.

Answer 1

By definition of "obtuse", one of the angles must be greater than 90
So if all 3 angles would be obtuse, their sum would be greater than 270°
But we know that the total sum of all 3 angles = 180°
So, silly conclusion.

As a matter of fact , a triangle can have only one obtuse angle, if it had 2 we would already have a sum of more than 180°
