Abstract
A multifunctional ruler and protractor tool with the ability to form and scale a near infinite number of geometric shapes. The tool comprises both a standalone ruler and protractor unit. Rulers are capable of being added to each other successively, creating straight ruler assemblies of virtually any length. The protractor unit can be slid onto a single ruler or a straight ruler assembly containing any number of consecutively connected rulers, and is capable of fastening another ruler to its sides by a quick connect/disconnect mechanism. The protractor component of the protractor unit pivots, allowing for the creation of angles between rulers that are laterally fastened and slidably engaged to it. The sliding lock on the protractor unit can arrest both rotational and translational motion of the protractor unit along any ruler, if it is manipulated to do so. Multiple rulers and protractors can be connected to form both open and closed, regular and irregular, polygons, and other sided geometric shapes. Geometric configuration can be scaled to larger or smaller sizes.
