What is how many obtuse angles are in an obtuse triangle?

An obtuse triangle is a triangle in which one of the angles measures more than 90 degrees. Therefore, an obtuse triangle will have one obtuse angle, which is also the largest angle in the triangle. The other two angles in an obtuse triangle will be acute angles, meaning they measure less than 90 degrees. So, in an obtuse triangle, there is always exactly one obtuse angle.
