Abstract
Compass constructions refers to standard procedures for constructing geometrical entities such as angle bisectors using compasses and straight edge only. These constructions are usually taught as a series of fixed steps without any justification of why the methods work. This article outlines a scheme of activities which provides links between the compass constructions required in the Singapore Mathematics Syllabus and other topics in the syllabus with extensions to problem solving.
