What you need to know:
Pythagoras’ Theorem is an equation that expresses a relationship between the 3 sides of any right-angled triangle. The equation is:
a^2 + b^2 = c^2
where c is the length of the hypotenuse, the longest side, and a, b are the lengths of the other two sides. It is required that you are able to rearrange this equation and use it appropriately to find any of the 3 possible missing sides of a right-angled triangle. You may also be asked to find the distance between two coordinates on a pair of axes, i.e. the length of the straight line between them. In this case, you can construct a right-angled triangle with the coordinates being either end of the hypotenuse, and use Pythagoras to find your answer.
