This lesson develops the concept of using Pythagoras’ theorem to derive the equation of a circle and translating between the geometric features of circles and their equations.

The initial activity involves looking at a circle with end points of the diameter at (6, 0) and (–6, 0). Questions relate to...

This lesson develops the concept of using the equation of a circle. In particular students develop their knowledge of how to:

• Translate between the equations of circles and their geometric features
• Sketch a circle from its equation

In the introductory activity a circle has been...

This teaching resource is presented in four stages:

Stage One - Finding out about the problem. In stage one pupils find out more about spacesuits, how they work and why people need them to survive. They also find out more about the challenge to test a series of materials to...
