Circles Inscribed in Equilateral Triangle in a Square Using Dr Geo (png image file)

Inscribe three equal circles in an equilateral triangle using dynamic geometry software. It is evident that: Three equal circles can be inscribed in an equilateral triangle, and each circle is in the centre of a square of which a side of the triangle is a side of the square. This construction originates from a spiral of half equilateral triangles, with a circle inscribed in each triangle. As an exercise, add more circles to this construction. The data file for Dr Geo is also on i2geo.net as Circlesinequilateralinsquare.drgeo
