tan (60) = √3/1 = 173 The right triangle is special because it is the only right triangle whose angles are a progression of integer multiples of a single angle If angle A is 30 degrees, the angle B = 2A (60 degrees) and angle C = 3A (90 degrees) The shortest leg must then measure $18/√3$ And the hypotenuse will be $2 (18/√3)$ Again, we are given two angle measurements (90° and 60°), so the third measure will be 30° Because this is a triangle and the hypotenuse is 30, the shortest leg will equal 15 and the longer leg will equal 15√3In 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

The triangle is a special right triangle, and knowing it can save you a lot of time on standardized tests like the SAT and ACT Because its angles and side ratios are consistent, test makers love to incorporate this triangle into problems, especially on the nocalculator portion ofA triangle is a special right triangle whose angles are 30º, 60º, and 90º The triangle is special because its side lengths are always in the ratio of 1 √32 Any triangle of the form can be solved without applying longstep methods such as the Pythagorean Theorem and trigonometric functionsThe Formulas of the Nature is Made of Triangles This calculator exists to compute the area of a triangle, where the three angles of the triangle measure 30, 60, and 90 degrees respectively, and only one other measurement is known
This method can be used to remember the triangle ruleThe property is that the lengths of the sides of a triangle are in the ratio 12√3 Thus if you know that the side opposite the 60 degree angle measures 5 inches then then this is √3 times as long as the side opposite the 30 degree so the side opposite the 30 degree angle is 5 /It turns out that in a triangle, you can find the measure of any of the three sides, simply by
