ABSTRACT:
An apparatus and method for a hinged measuring and marking device is disclosed herein. The device utilizes a first member, containing a flat surface with a straightedge for marking or measuring, coupled to a second member, also containing a flat surface with a straightedge for measuring or marking wherein the first member is coupled to the second member in a direction perpendicular to the straightedge of the first member. The straightedges of the first and second members are coplanar for marking an approximately contiguous line on a single plane or on two intersecting planes. The first member and the second member can be rotated between 0 and 180 degrees with respect to each other to accommodate marking a line on the two intersecting planes.
