If you want to know what is the hypotenuse of a right triangle, how to find it and what is the hypotenuse of a triangle formula, you'll find the answer below, with a simple example to clear things up Don't wait any longer, give this hypotenuse calculator a try!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, andThe reason these triangles are considered special is because of the ratios of their sides they are always the same!
Right triangles are one particular group of triangles and one specific kind of right triangle is a right triangle As the name suggests,A 30 60 90 triangle is a special type of right triangle What is special about 30 60 90 triangles is that the sides of the 30 60 90 triangle always have the same ratio Therefore, if we are given one side we are able to easily find the other sides using the ratio of 12square root of three 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/2 b = c√3/2 Or simply type your given values and the 30 60 90 triangle calculator will do the rest!
A triangle is one of the few special right triangles with angles and side ratios that are consistent and predictable Specifically, every triangle has a 30º angle, a 60º angle, and a 90º angle Since these angles stay the same, the ratio between the length of the sides also remains the same 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) Since the right angle is always the largest angle, the hypotenuse is always the longest side using property 2 We can use the Pythagorean theorem to show that the ratio of sides work with the basic triangle above a2b2=c2 12(3–√)2=13=4=c2 4–√=2=c
