Virtual manipulatives encourage creativity and increase the variety of students' solutions (Moyer-Packenham & Westenskow, 2013). Working with examples on computers enable students to experiment or "play" with the problem. This allows students to take an inductive, rather than deductive, approach to proof writing and problem solving. (Shaffer & Kaput, 1999).
This manipulative displays a complicated set of relationship in triangles. As students drag points, they will start to notice properties of these relationships. They can check these properties my forming constructions and taking measurements with the tools provided. These explorations will also help them understand why the properties hold true and better prepare them for formal proof writing.
