The word hypotenuse comes from a Greek word hypoteinousa which means ‘stretching under’. The hypotenuse is the longest side of a right angled triangle and is opposite to the right angle.
Formula to calculate the length of the hypotenuse.
The method below is known as the pythagorean theorem. Whereby, to find the hypotenuse of the triangle, you square(multiply a number by itself) the base (a²) and the height (b²) and then add them together to get the square of the hypotenuse (c²). Then find the square root of ‘c²’ to get the length of the hypotenuse.
Calculate the hypotenuse of the following right angled triangle.
Therefore , the hypotenuse of the triangle is 5 cm.
