If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
A triangle with 1 right angle is a right angle triangle.
An obtuse triangle has an obtuse angle.
A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
A 90o angle is also called a Right Angle, so a triangle that has one 90o angle is a Right angle triangle.
