PYTHAGORAS

There is a rule connecting the side lengths of right-angled triangles. It is called Pythagoras' theorem, and it is true for all triangles with a right-angle. Finding one side of a right-angled triangle when you know the other two

SIMULTANEOUS EQUATIONS

Sometimes you will be asked to find 2 unknown values by solving 2 equations at the same time. These types of equations are called simultaneous equations. These questions have two equations with two unknown values!
