A right triangle with a 30 angle or 60 angle must be a 30 60 90 special right triangle. A 30 60 90 right triangle is a special right triangle in which one angle measures 30 degrees and the other 60 degrees. Although all right triangles have special features trigonometric functions and the pythagorean theorem.
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 degrees. In a triangle whose angles measure 30 0 60 0 and 90 the hypotenuse has a length 0 equal to twice the length of the shorter leg and the length of the longer leg is the product of 3 and the length of the shorter leg. In an isosceles right triangle the angle measures are 45 45 90 and the side lengths create a ratio where the measure of the hypotenuse is sqrt 2 times the measure of each leg as seen in the diagram below. The ratio of the sides of a 30 60 90 triangle are.
Special right triangles 30 60 90. A 30 60 90 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 easy to remember ratio. X 3 2 x.
Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 8 inches and one of the angles is 30.
