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.
Right Triangles. A right triangle is a triangle where one of its angles is a right angle (i.e. 90Â°). The other two angles are acute angles. You may have noticed that the side opposite the right angle is always the triangle's longest side. It is called the hypotenuse of the triangle.The other two sides are called the legs.or example, in trigonometry and also in the Pythagorean Theorem. The lengths of the sides of a right triangle are related by the Pythagorean Theorem. There are also special right triangles where the sides are of certain fixed ratios. A right triangle can be isosceles if the two legs are equal in length.
