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.
For any angle in the triangle that is not a right angle, the opposite side is the side does not touch the angle and the adjacent side touches it and is perpendicular to the opâ¦posite side. The third side is the longest side and is the hypotenuse. 1 person found this useful. Ohteri.
