You will see a number of questions we have received where our response uses the Pythagorean theorem. For your second question place two points P and Q on the Cartesian plane and add a third point R so that triangle PQR is a right triangle with PQ the hypotenuse. Write the lengths of PR and RQ using the coordinates and then apply the Pythagorean theorem to this triangle. Harley
