DUAL SPEED SQUARE

A dual speed square has a first triangle member, a second triangle member, and an intermediate connector. The first triangle member and the second triangle member are each laterally and hingedly connected to the intermediate connector opposite each other through a first hinge joint and a second hinge joint, respectively. The triangle members rotate respective to the intermediate connector between a deployed configuration and a stored configuration. In the deployed configuration, the triangle members may be placed on opposite sides of a workpiece in order to identically mark out the opposite sides of the workpiece. In the stored configuration, the triangle members are positioned adjacent to each other, occupying a smaller space than in the deployed configuration for easier transport and storage.
