If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle

As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.

Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.

All three interior angles of a spherical triangle may be right angles.

Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
