The module is compact in size and design for ease in carrying on one's person and, it may be attached to a framing square or a straight edge, for example, such that measuring of the horizontal, vertical, and acute or obtuse angles may be readily accomplished in a portable fashion. In another mode, the measuring module which is formed upon a four-sided support member may be utilized without any additional structural element to provide a self contained angular measuring mechanism.
