Abstract
A squaring device comprises two reels of tape rotatably mounted on a support, the axes of rotation of the reels being inclined to each other to enable the tapes to be unreeled at an acute angle to each other. The two reeled tapes are connected by gearing to effect simultaneous unreeling of the tapes in a predetermined ratio to each other. Preferably this ratio is a linear function of the cosine of the acute angle whereby the device, or two of these devices connected together, can be used to form a right angled triangle in performing squaring operations, depending upon the linear function. In this way the squaring operation can be performed without the need to make measurements or perform calculations.
