For example, the opposite sides formed by segment A

_{12}A

_{14}and segment A

_{23}A

_{34}seem to naturally go together with the opposite sides formed by segment A

_{12}A

_{23}and segment A

_{14}A

_{34}.

Likewise, the opposite sides formed by segment A

_{23}A

_{24}and segment A

_{13}A

_{14}seem to naturally go together with the opposite sides formed by segment A

_{13}A

_{23}and segment A

_{14}A

_{24}.

When you construct segments connecting the midpoints of these three sets of opposite sides, the segments intersect in collinear points.
