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.
Version
Other similar applications	Cabri Geometry Kig (software)
The application on mobiles and tablets	Phone application not available. It is a web base application.
Development and community help	Developed by MathDisk Technologies http://robocompass.s3.amazonaws.com/docs/RoboCompass_Handout_Edited.pdf

Overview of features
