An illustration shows an equilateral hexagon with a closed circle at each vertices. Two closed circles are shown in between every two vertices which are equidistant. A line is drawn from the center of the hexagon to the third vertex. A second line runs from the closed circle next to the fifth vertex and joins the other line at the center of the hexagon.

An illustration shows an equilateral hexagon with one diagonal line drawn from two vertices that splits the hexagon equally through the center. A second line is drawn in between two vertices and intersects with the first line, splitting the hexagon into 4 equal parts.
