Embodiment Construction

[0028] The three-dimensional shape of a regular tetrahedron is formed by the combination of six identical parts, Part 1, Part 2...Part 6; the dotted line is used to represent the positive fold line of the front half, that is, when folding, the front and the front of the paper are folded relative to each other; the solid line is added The circle indicates the anti-folding line of the back-folding, that is, when folding, the back side of the paper and the back side are folded relative to each other; the dots on the solid line indicate the indicator line;

[0029] Take a rectangular paper with a ratio of horizontal length, vertical width, length to width 1.1:1, and make two vertical lines, that is, the left and right vertical indicator lines, and the two vertical lines divide the rectangular paper into three small rectangles: left, middle, and right; Two horizontal lines, i.e. the upper and lower horizontal indicator lines, intersect with the two vertical lines, forming three hori...

Abstract

The invention discloses a regular tetrahedron solid figure, and relates to a manufacturing method of the solid figure. The regular tetrahedron solid figure is combined by six identical parts; rectangular papers with length-width ratios of 1.1: 1 are taken for folding a first hexagon and a second hexagon; parts having inserting parts and inserted parts are produced; two parts are inserted as follows: the inserting part of the part 1 is inserted in an inserted opening of the inserted part of the part 2; intersecting points of inserted to the inserting parts and the inserted parts are overlapped; short reverse folding lines of the inserting parts and long reverse folding lines of the inserted parts are overlapped; three parts can be inserted to form a combined angle or a triangular plane; and the six parts are inserted to form the regular tetrahedron solid figure having four combined triangular planes and four combined angles. The regular tetrahedron solid figure is skilful and simple in design, is simple in part folding, is easy in combination and insertion, is strong in geometric shaping stereoscopic impression, and is firm.

Description

technical field [0001] The invention relates to a method for making a geometric body, in particular to a method for making a three-dimensional shape. Background technique [0002] At present, the known tetrahedrons are mostly made by bonding, and regular tetrahedrons formed by plugging multiple parts are rare. Contents of the invention [0003] In order to overcome the shortcomings that the existing tetrahedron production methods are mostly glued, and regular tetrahedrons formed by plugging multiple parts are rare, the present invention provides a three-dimensional production method of regular tetrahedrons. [0004] The technical solution adopted by the present invention to solve the technical problem is: the regular tetrahedral three-dimensional shape is formed by the combination and plugging of a total of six identical parts from part one, part two...part six; [0005] Take a rectangular paper with a length-to-width ratio of 1.1:1, and make two vertical lines, that is, ...
