Abstract

Performing constructions of geometrical figures using a compass and straight edge (that is, a ruler without markings) are an integral part of learning mathematics at school. These are typically introduced in the middle school and students generally enjoy this topic as it gives them an opportunity to work with their hands. Teachers spend a significant amount of time teaching the “steps of construction” which students follow as an algorithm to arrive at the correct constructed figure. However, this approach does not leave much scope for exploration of figures and their geometrical properties. In this article, we shall illustrate the opportunities provided by GeoGebra, a Dynamic Geometry Software (DGS), in exploring constructions of simple geometrical figures through multiple approaches.
