Abstract
The utility model relates to a multi-purpose tetragonal ruler which comprises a 30-degree right-angle set square, and is characterized in that an angle protractor is engraved on the bevel edge of the 30-degree right-angle set square, and a 45-degree isosceles right-angle set square is internally arranged on the short right angle side of the 30-degree right-angle set square. The multi-purpose tetragonal ruler has the beneficial effects that the 30-degree right-angle set square, the 45-degree isosceles right-angle set square and the angle protractor which are commonly used are combined into a whole, so that the defect that the three tools are inconvenient to carry and easy to lose is solved, the manufacturing material is saved, and the multi-purpose tetragonal ruler is energy-saving and environmentally friendly.
Description
Technical field
The utility model belongs to study article, particularly is applicable to students in middle and primary schools' study article.
Background technology
Various set squares, protractor are the most frequently used learning tools of students in middle and primary schools, and 30 degree right angle triangles, 45 degree isosceles right angle triangles, carrying to students in middle and primary schools of protractor are made troubles, and lose easily, influence the normal use of students in middle and primary schools' study.
The utility model content
Spend the inconvenience of carrying of isosceles right angle triangles, protractor in order to overcome 30 degree right angle triangles, 45, and the deficiency of losing easily, the purpose of this utility model provides a kind of multi-functional Square consisting of two isosceles right-angled triangles, this multi-functional Square consisting of two isosceles right-angled triangles, the student uses very convenient, does not need to dispose in addition set square, protractor.
The technical scheme in the invention for solving the technical problem is: a kind of multi-functional Square consisting of two isosceles right-angled triangles, comprise 30 degree right angle triangles, it is characterized in that: scribing protractor on 30 degree right angle triangle hypotenuses, 45 degree isosceles right angle triangles are built on the short right-angle side of 30 degree right angle triangles.
The beneficial effects of the utility model are that 30 degree right angle triangles commonly used, 45 degree isosceles right angle triangles, protractor are combined into one and have solved the deficiency of carrying inconvenience and losing easily of three kinds of stationery, it is one that 30 degree right angle triangles, 45 degree isosceles right angle triangles, protractor close three, save and make material, energy-conserving and environment-protective.
