What is the Pythagoras Theorem?

The Pythagoras Theorem equation is:

a+ 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 - b= a2

c- a= b2

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