Is This Elegant Property of Equilateral Triangles a New Discovery, or Has It Been Known for Centuries?
Consider the equilateral triangles ABC, CDE, and ADF. G is the midpoint of AB, and H is the midpoint of DE. Prove that the area of triangle ADF is twice that of quadrilateral AGDH.
			
    		
Midpoints interlace,
Triangles echo their form,
Twice the shape revealed.
