What is Pythagorus Theorem ? Find the length of BC if given a right angle triangle ABC where AB is 8cm and the length of the hypotenuse AC is 10cm ?

Pythagorus Theorem states that the side of a 'Right Angled Triangle' can be found by using the formulae c= a2 + b, where c is considered as hypotenuse. In our case the hypotenuse is AC and by putting it in order we get AC= AB+ BC2. Start putting the legths provided we have 10= 8+ BC2 and Rearranging gives us: BC= 10- 82. BC= 100 - 64. BC= 36. BC = √36.  BC = 6 So, the length of the side BC is 6cm.
