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.
An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles. A scalene triangle has no sides of equal length and no equal angles. A right angle triangle has one angle that is 90 degrees.An obtuse triangle has one angle larger than 90 degrees. An acute triangle has angles that are all less than 90 degrees.The longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.Trigonometry is the study of the relationship between the angles of triangles and their sides. Triangle shapes are often used in construction because of their great strength.he longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.
