Learn Robo-compass
Introduction
Robo-compass is an online Geometry tool for creating constructions. It allows users to make simulations of geometric constructions. The animations are exactly as we do using a physical straightedge, compass and protractor. The construction can be viewed any number of times.
| ICT Competency | This is a tool for creating resources for mathematics constructions. |
| Educational application and relevance | It is possible to create drawings and animations using Geogebra to explain different concepts in geometry and algebra. It can be used by teachers as an interactive construction board in the classroom for demonstration and student learning. |
