The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Their angles are also typically referred to using the capitalized letter corresponding to the side length: angle A for side a, angle B for side b, and angle C (for a right triangle this will be 90°) for side c, as shown below. Enter three side lengths and one angle between two of those sides. Calculator to calculate the area of a trapezoid given the bases and the height. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
