Transformation of Square based on Spiral of Triangles (Dr Geo geometry file)

This transformation of a square originates from a spiral of half equilateral triangles (30°-60°-90° triangles) positioned recursively, with the side of one triangle being equal in length to the hypotenuse of the next. A circle is inscribed in each triangle. The circle in the second triangle is in the centre of the first square. File type drgeo for the Dr Geo dynamic geometry software. A coloured png image file is also on as Spiraltransformationofsquare.png
