This interconnecting ruling system allows users to create multi-sided shapes of many sizes and proportions. Angles and shapes are formed by selectively snapping rulers into sliding protractors and scaling to desired configurations. The ruler displays simultaneous side and angle measurements in inches (1/16 increments) on one side and centimeters on the other. It provides the ability to form and scale polygons of virtually any shape configuration. Users can selectively lock angles and snap the rule segments end-to-end to extend side lengths.
