Geometrical Constructions
Bayani Gaba-gaba
Some geometry is done not by calculation but by careful drawing. With nothing more than a ruler, a protractor and a pair of compasses you can measure an angle, build an accurate triangle from three lengths, and unfold a solid into a flat net. These are practical skills, and accuracy is everything.
In this lesson you will learn to measure and draw lines and angles, to construct a triangle from three given sides using compass arcs, and to draw and read the nets of simple solids. Each method is set out as a clear, ordered list of steps you can follow with instruments in hand.
Manufura
- Measure and draw lines and angles.
- Construct a triangle, given the lengths of all sides, using a ruler and pair of compasses only.
- Draw, use and interpret nets.
