Construction and Scale drawing
Most object around us are born on the table of a designer. Before anything is made or produced, it has been accurately drawn on a piece of paper on somebody's attic or at the office. Although most of these drawings are done on computers now, designers still use mathematical concepts and geometrical relationships to do so properly. In other words, everything manmade around you is based upon our understanding of geometry and maths. In this section you will learn how to construct all sorts of figures using your compass, protractor and rules. First of all you will understand how to construct various polygons accurately like triangles and parallelograms. But if you want to pass your IGCSE GCSE maths exam you will also need to learn how to construct Bisectors. Study the videos therefore carefully which will explain to you how to construct an angle bisector and a line bisector (perpendicular bisector) using your protractor, compass and ruler. Finally I will show you an example question of what is meant with Scale Drawing. Good luck and have fun!
