Abstract
A rule for linear and angular measurements, constituted by a rectangular surface, made of metal sheet, paste, wood or appropriate material, of suitable width and variable length, with the millimeter edges, and one of them with a bevel, so that this angle and the fold made on the opposite side, give rigidity to the rule when it is made of sheet metal; in the central part and near the non-beveled edge, an arm rotates, of variable length, which is another small ruler, also millimeter, which by means of an extension above the axis, which runs through a graduated semicircle, indicates the Angle opening forming the fixed and movable rule. Several regular polygons are represented next to their corresponding angles. (Machine-translation by Google Translate, not legally binding)
