A triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle) Because the angles are always in that ratio, the sides are also always in the same ratio to each other The side opposite the 30º angle is the shortest and the length of it is usually labeled as x The side opposite the 60º angle has a Triangle Rules How do we know that the side lengths of the triangle are always in the ratio 1 3 –√ 2 ? Side length rules for a triangleHowever a triangle with angles 30, 60 and 90 degrees has a property that allows you to solve your question without resorting to trigonometry The property is that the lengths of the sides of a triangle are in the ratio 12√3Although all right triangles have special features – trigonometric functions and the
