Abstract

In this article we shall describe how grade IX students visualised the Euler’s circle (more popularly known as the nine-point circle) of a triangle, using GeoGebra. The journey undertaken by them as they constructed the figure, made conjectures and finally arrived at the proof will be discussed.
