Drawing Instruments and Material III
Performance Objectives
Students should be able to:
- Construct shapes e.g. Circles, Triangles, Rectangles with drawing instruments and materials
Content
Geometrical constructions should be drawn with a sharp, hard (2H) pencil. A pencil eraser, a ruler marked in centimetres (often used as a straight edge), a pair of compasses, two set squares (90°, 60°, 30° and 90°, 45°, 45°) and a protractor with a radius of at least 5cm make up the basic set of geometrical instruments.
Using Compasses to Draw a Circle
Suppose we are given an interval AB and a point O. In geometry, we always include the endpoints in an interval.
