Draw an Equilateral Triangle ABC and draw an other Equilateral Triangle DEF inside the ABC such that the Apex of DEF intersects the midpoint of the triangle ABC. Then remove the bottom portions of DEF to the apex of DEF and the Apex of ABC. This creates two more Equilateral Triangles A, midpoint, B and A, midpoint, C. This creates two Equilateral side Triangles.
