A 30–60–90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degreesBecause it is a special triangle, it also has side length values which are always in a consistent relationship with one anotherThe hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle The longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by the squar Continue Reading A triangle is special because of the relationship of its sidesIn a triangle, the ratio of the sides is always in the ratio of 1√3 2 This is also known as the triangle formula for sides yy√32y Let us learn the derivation of this ratio in the triangle proof section Consider some of the examples of a degree triangle with these side lengths
