What is the Pythagoras Theorem?

The Pythagoras Theorem equation is:

a²+ b² = c²

^{It is used to calculate an unknown side of a right angled triangle. a, b and c represent sides of the triangle and you can rearange the formula to find whichever side you are looking for.}

c²- b²= a²

c²- a²= b²

Once you have found what a²or b² or c² is you then simply square root that number to find the length of your side.
