A right-angled triangle is a triangle in which one of the angles is 90°. The side which is opposite the 90°-angle is called the hypotenuse (marked x in the triangle) and the others are called opposite and the adjacent.
With the help of the Pythagorean theorem, we can write a relation between the sides of a right-angled triangle
This equation gives us that
