The interior angles of a triangle always add up to 180 degrees. If you make one angle bigger, another angle will become smaller: The exterior angles of a triangle always add up to 360 degrees: In every triangle, the shortest side is always opposite the smallest interior angle. The longest side is always opposite the largest interior angle. âOppositeâ means that the side does not touch the point of the angle on either end. Equilateral triangles must have three angles of 60 degrees each, and all triangles with three 60 degree angles are equilateral.
Assign the variables a, b, and c to the sides of your triangle. The hypotenuse (longest side) must be c. For the sake of simplicity, label the side with the known length as a, and the other b. Then assign variables A, B, and C to the angles of the triangle. The right angle opposite the hypotenuse will be C.
