The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle. The sum of the length of any two sides of a triangle is greater than the length of the third side. Sum of angles of the triangle is equal to 180 degrees. Exterior angles of a triangle add up to 360 degrees. Shortest side is always opposite the smallest angle of a triangle.
