A tool for equally dividing a circle and its application method

Abstract

The invention provides a tool for equally dividing a circle and its use method. By using a new tool which is deformed and improved on the basis of an existing common drawing tool, the known circle is expanded into a line segment, and after the line segment is equally divided, Then, through the bisection point of the line segment, find the bisection point of the circle to realize any n (natural number) bisection of the known circle. Error; at the same time, it also naturally solves the problem of dividing the known arc and the known angle into n equal parts, making a regular n-gon in the known circle, making a circumscribed regular n-gon in the known circle, and drawing on the number axis Find out the position of π, draw a circle with a known circumference, etc., the present invention also changes the mode of angle measurement, can draw a theoretical 1 / n degree, n can be any natural number, which cannot be realized with a protractor of.

Description

technical field [0001] The invention belongs to the technical field of drawing, and relates to a tool and a method for equally dividing a known circle by any n (natural numbers), in particular to a tool for equally dividing a circle and a use method thereof. Background technique [0002] At present, in the fields of scientific research, teaching, surveying and mapping, mechanical engineering, etc., it often involves n equal divisions of a known circle, or n equal divisions of a known angle or arc, and doing it in a known circle. Inscribed regular n-gon, or circumscribed regular n-gon, etc. For these problems, in the existing drawing tools (including software tools), any single tool or combination of tools cannot theoretically realize arbitrary n equal divisions, only part of them can be realized, for example, when n=2n, 3, 4, 5, etc. a few can be achieved. [0003] For the n (natural number) equal division of the circumference, there is no theoretical or practical operatio...

Problems solved by technology

For these problems, in the existing drawing tools (including software tools), any single tool or combination of tools cannot theoretically realize arbitrary n equal divisions, only part of them can be realized, for example, when n=2n, 3, 4, 5 and a few can be realized

[0003] For n (natural number) equal division of the circumference, there is no theoretical or practical operation that can divide a known circle n (natural number) equally; similarly, there is no theory or actual operation that can divide a known circle Arc n (natural number) is equally divided; similarly, there is no theory or practical operation that can divide a known angle n (natural number) equally
