For a triangle to be obtuse only one of the angles must br shown to be obtuse. (in fact only one of the angles can possibly be obtuse) but for a triangle to be acute all three angles must be shown to be acute. explain why determining one acute angle with the pythagorean inequalities theorem shows that the triangle is acute
