This program presents the ideas of similarity, ratio and proportion in a refreshing and informal style. Examples are drawn from everyday life using familiar objects with on-screen graphics producing clear well defined diagrams. Thorough explanations are provided with worked examples and student practice is also included. Methods to obtain indirect measurements are simplified and elegantly demonstrated, including surveying methods to find the width of a river and a mirror to find the height of a tall object. Both of these methods are suitable for student activities and use readily obtainable equipment.
