Since a triangle has 3 angles that total 180 degrees, it can have only 1 right angle. Since a triangle has 180 degrees and 3 angles, it can only have 1 right angle.
In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: 1  Less than 90Â° - all three angles are acute and so the triangle is acute. 2  Exactly 90Â° - it is a right triangle. 3  Greater than 90Â° (obtuse): the triangle is an obtuse triangle.
