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 Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle). right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90- degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
