Abstract
A flat triangular piece, usually of shatter resistant plastic, is formed with straight edges and is used in connection with a T-square for drawing perpendicular lines and geometric shapes. The outside peripheral corners are rounded for safety purposes and the intermediate portions of the legs are slotted or recessed to permit the utilitarian reproduction of triangular lines and shapes with sharp points.
