Model description

An educational model for learning about the relationship between angles. The set consists of 3 identical number lines, which can be connected with bolts and nuts from SkriKit. When connected, the number lines will form a triangle with movable sides - the sides can be moved relative to each other, thus creating triangles with different angles.

The model will be particularly useful in Maths classes and when working with students with special educational needs.
