Abstract

The invention discloses a method for evenly dividing a circumference. The method is characterized in that a first ruler body and a second ruler body which are hinged with each other are included; the sharp end A of the first ruler body and the sharp end B of the second ruler body are respectively aligned with two ends of the diameter of a circle to be divided into m parts evenly; the distance from the hinged end P on the first ruler body to the sharp end A is PA; a first even dividing ruler is provided with t evenly dividing scales; the distance from the t evenly dividing scales to the sharp end A is PAsin alpha; alpha is a 2t even dividing angle of 360 degrees; t is a natural number greater than 1; a rotating end D of a telescopic ruler body parallel to the second ruler body is aligned with the t evenly dividing scales; the point of intersection of a sharp end C and the diameter is the m evenly dividing point; AC is the evenly dividing length of the evenly divided circumference; t is greater than m; m is a natural number greater than 1. The invention further discloses a multiple divider for evenly dividing the circumference. The circumference can be rapidly and evenly divided.

Description

technical field [0001] The invention relates to the field of rulers and gauges, in particular to a method for equally dividing a circle and an equally dividing rail. Background technique [0002] In teaching or drawing, to equally divide any circle, the measurement method is generally used, and the rulers are used to measure and mark according to the equal fractions to be equally divided. The above equal division method wastes teaching or drawing time, especially in the case of odd equal division, which is more complicated and time-consuming. Contents of the invention [0003] The invention proposes a method for equally dividing a circle and an equally dividing rail, which can simply and conveniently divide a circle to be equally divided into equal parts. [0004] Technical scheme of the present invention is realized like this: [0005] A method of equally dividing a circle, comprising a first scale body and a second scale body hinged to each other, aligning the tip A of...
