A right triangle is a type of triangle that has one angle measuring exactly 90 degrees. The side opposite this 90-degree angle is called the hypotenuse, which is the longest side of the right triangle ...

Pythagoras’ theorem can also be used to find the length of another side of a triangle using the hypotenuse. The square on the hypotenuse subtracted by the square on another side is equal to the square ...

Pythagoras’ theorem allows us to calculate the length of any side of a right-angled triangle given the other two. The square of the hypotenuse is equal to the sum of the squares of the remaining two ...
