A 30-60-90 triangle is a special right triangle with some very special characteristics. If you have a 30-60-90 degree triangle, you can find a missing side length without using the Pythagorean theorem!
The algorithm of this right triangle calculator uses the Pythagorean theorem to calculate the hypotenuse or one of the other two sides, as well as the Heron formula to find the area, and the standard triangle perimeter formula as described below. Moreover it allows specifying angles either in grades or radians for a more flexibility. The sides of a right angle triangle are in the ratio 3:4. A rectangle is described on its hypotenuse being the longer aide of the rectangle. The breadth of the rectangle is4/5 of its length . Find the shortest side of the right triangle if the perimeter of the rectangle is 180 cm

The hypotenuse is twice the length of the shortest leg which is 2⋅2√3 or 4√3 . 3-4-5 Right Triangle Unlike the 45-45-90 triangle and the 30-60-90 triangle where you only need to know one side length to find the other two side lengths, you will have to know two of the side lengths to find the third side length in a 3-4-5 triangle.
Given: Isosceles right triangle XYZ (45°-45°-90° triangle) Prove: In a 45°-45°-90° triangle, the hypotenuse is times the length of each leg. Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, a2 + b2 = c2, which in this isosceles triangle becomes a2 + a2 = c2. By combining like terms, 2a2 = c2.
