How Many Angles Are in a Triangle?

No matter what type of triangle is in question, there are always three angles in a triangle. The angle sizes vary on the type of triangle, but there are always three that add up to 180 degrees.

If the triangle is an equilateral triangle, then all three angles are exactly 60 degrees each. A right-angled triangle has one angle of 90 degrees, which is the right angle, with two more angles that total 90 degrees when added together. Any triangle that has two equal angles is called an isosceles triangle. A triangle whose angles are all different sizes is a scalene triangle.
