Geometric Constructions
Gbogbo ọrọ náà
A formal geometric construction uses only a pair of compasses and a straight edge, no protractor, no ruler markings. With those two tools you can bisect a line exactly in half, or split an angle into two equal parts, with perfect accuracy.
In this lesson you will make the two key constructions the syllabus asks for: the perpendicular bisector of a line segment and the bisector of an angle. Understanding why each set of arcs works makes the steps easy to remember and reproduce.

- Make formal geometric constructions with a compass and straight edge, such as a perpendicular bisector and an angle bisector.
