ExplanationA right-angled triangle is a triangle where one of the angles is a right angle (90 degrees). The hypotenuse is the longest side of a right-angled triangle, and it is always opposite to the right angle. The other two sides are called the legs, often referred to as base and height.

The area of the right-angled triangle is:

Area=bh2Area = \frac{bh}{2}Area=2bh​
✍️ Algebraic proof of area formula
To calculate the length of the hypotenuse, we can use the Pythagorean theorem. Check out our page on Pythagorean theorem for an in-depth explanation. It's important to note that the Pythagorean theorem only applies to right-angled triangles.
The length of the hypotenuse is:
﻿
Hypotenuse length=b2+h2Hypotenuse\space length=\sqrt{b^2+h^2}Hypotenuse length=b2+h2​
