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.
The longest side of a triangle is opposite the largest angle of a triangle. Conversely, the smallest side of a triangle is opposite the smallest angle of a triangle. Consider the following example: Rank the size of the angles of triangle ABC from largest to smallest.Since side AC is the longest side, angle B is the largest angle.Since side AB is the next longest side, angle C is the next largest angle. Since side BC is the shortest side, angle A is the smallest angle.ank the size of the angles of triangle ABC from largest to smallest. Since side AC is the longest side, angle B is the largest angle. Since side AB is the next longest side, angle C is the next largest angle. Since side BC is the shortest side, angle A is the smallest angle.
