PARALLELOGRAM VS PARALLELOCHRON

A parallelogram is a quadrilateral whose pairs of opposite sides are equal and parallel two to two. Parallelograms are square, rhombus, rectangle and rhomboid. Parallelogram is a figure of space and parallelochron is a figure of change or occurrence of phenomena.

Parallelochron is a figure that has one arrow at one end and has two equal parallel longitudinal sides. On the left side duration begins and on the right side duration continues (arrow). One of the longitudinal sides represents the duration of irregular rhythm and the other longitudinal side represents the duration of regular rhythm (time).
