You've looked a lot at shapes in KS3 Maths. This particular quiz on shapes looks at the special number relationship linking the lengths of the sides of a right-angled triangle. This relationship is named after the ancient Greek mathematician, Pythagoras.
Pythagoras' Theorem says that, in right-angled triangles: 'The square on the hypotenuse (that's the longest side which will be opposite the right angle) is equal to the sum of the squares on the other two sides'. Because this rule is true for every right-angled triangle, you can use it to test whether a triangle whose angles you don't know (so long as you do know the lengths of the sides) has a right angle. That will come in handy in this quiz!
You may find it helpful to draw some diagrams while doing this quiz. So, get your pencil and paper out and see how well you can do. Take your time and read each question carefully before you choose your answers. Good luck!
