Pythagoras Theorem is one of Maths most enjoyable theories. This theorem is used when we have to find the Hypotenuse ( the opposite side of the base and altitude of a right angle triangle [ see image ]). This only works when one angle is 90 degrees or right angled. The formula states that the sum of the base squared and the altitude squared is equal to the hypotenuse squared! If we wrote this as a mathematical formula, it would be : a2 + b2 = c2, where a is the base, b is the altitude and ...
