Therefore, if we are given one side we are able to easily find the other sides using the ratio of 1:2:square root of three. The smallest side (1) is opposite the smallest angle (30 degrees). Students also learn that in a 30°-60°-90° triangle, the length of the long leg is equal to root 3 times the length of the short leg, and the length of the hypotenuse is equal to 2 times the length of the short leg. This relationship is useful because if two sides of a right triangle are known, the Pythagorean theorem can be used to determine the length of the third side. More accurately, the sides have a ratio of x, x√3, and 2x with respect to each other, where “x” equals the length of the shortest side. An equilateral triangle is a special case of isosceles triangles. An isosceles right triangle therefore has angles of 45 degrees, 45 degrees, and 90 degrees. As all the three angles are equal, the triangle is an equilateral triangle. The well-known equation for the area of a triangle may be transformed into a formula for the altitude of a right triangle: a r e a = b × h / 2.
