Using the Blue Triangles children learn the basics of surface geometry. Each pair of triangles has at least one side of the same length and thus can be placed to make a new shape.

Besides the different triangle types the children learn different quadrilaterals (square, rectangle, trapezoid, ...). 

A great preparation for further exercises in the field of geometry.
