Abstract

The invention discloses a multifunctional angle measuring and drawing device which comprises a complete protractor (1), a cut protractor (2) smaller than a half circle, a cut protractor (3) larger than a half circle and a fixing nail (4). The multifunctional angle measuring and drawing device is characterized in that a protractor is cut along an inner arc, an outer arc is correspondingly adhered with another complete protractor, and the inner arc is nailed with the center of an adhered double-layer protractor by the fixing nail (4). The multifunctional angle measuring and drawing device has the advantages that each protractor is provided with a movable side and a static side, and angles formed by the movable sides and the static sides are equal to angles with pointed reading numbers by the aid of a vertex angle equation principle; the problem of trouble in drawing angles by the aid of an existing protractor can be solved by the aid of the multifunctional angle measuring and drawing device, and the multifunctional angle measuring and drawing device is an efficient assistant for extensive students in learning life.

Description

technical field [0001] The invention relates to an angle measuring instrument, in particular to a multifunctional angle measuring device. Background technique [0002] In the daily learning process, using a protractor to draw an angle with a specified reading is a cumbersome process that requires steps such as drawing lines, aligning points, and connecting lines. It requires multiple use of pens and protractors, as well as a ruler. In order to simplify this process, it is necessary to make further improvements. Contents of the invention [0003] The present invention can solve the above problems, and provides a multifunctional device for measuring angle of view. [0004] The object of the present invention is achieved in that a multifunctional protractor is made up of a complete protractor, a small semicircle protractor of a cut, a large semicircle protractor of a cut, and fixing nails. Cut a piece of protractor along the inner arc, glue the outer arc to another piece of...
