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 incenter of a triangle is the point where the three angle bisectors meet. This point is the same distance from each of the three sides of the triangle. An inscribed angle is an angle whose vertex is on a circle and whose rays intersect the circle. An intercept is an intersection of a graph with one of the axes.
