A right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees The triangle is significant because the sides exist in an easytoremember ratio 1 √3 3 2 That is to say, the hypotenuse is twice as long as the shorter leg, andHow to use a special right triangle () to solve problemsCheck out this tutorial to learn about triangles!

The 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 /A triangle is a right triangle where the three interior angles measure 30 °, 60 °, and 90 ° Right triangles with interior angles are known as special right triangles Special triangles in geometry because of the powerful relationships thatThis page shows to construct (draw) a 30 60 90 degree triangle with compass and straightedge or ruler We are given a line segment to start, which will become the hypotenuse of a right triangle It works by combining two other constructions A 30 degree angle, and a 60 degree angleBecause the interior angles of a triangle always add to 180 degrees, the third angle must be 90

30 60 90 triangle sides If we know the shorter leg length a, we can find out that b = a√3 c = 2a If the longer leg length b is the one parameter given, then a = b√3/3 c = 2b√3/3 For hypotenuse c known, the legs formulas look as follows a = c/2Then ABD is a 30°–60°–90° triangle with hypotenuse of length 2, and base BD of length 1 The fact that the remaining leg AD has length √ 3 follows immediately from the Pythagorean theorem The 30°–60°–90° triangle is the only right triangle whose angles are in an arithmetic progressionTriangles are classified as "special right triangles" They are special because of special relationships among the triangle legs that allow one to easily arrive at the length of the sides with exact answers instead of decimal approximations when using trig functions
