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.
Different Types of Triangles. The different types of triangles are grouped by either their angles, lines or both. For example and equilateral triangle is a triangle whose SIDES are equal. A right triangle has one angle that is 90 degrees, also known as a right angle. An Isosceles triangle is a triangle which has two sides equal in length. But you can also have a Right Isosceles triangle.
