Abstract
The utility model relates to a mathematical angle metering ruler. At present, rulers used by people include meter rules, straight scales, set squares, measuring tapes, tape measures, T-squares and so on; however, most of those have single function, which cannot satisfy needs of teaching and learning of mathematics. The mathematical angle metering ruler comprises a main scale (1), wherein one end of the main scale is fixedly connected with an angle meter (2) of 180 degrees; the bottom edge of the main scale and the angle meter of 180 degrees are in one identical straight line; and the other end of the main scale is fixedly connected with a semicircular ruler (3). The mathematical angle metering ruler is used for mathematical drawing.
Description
Technical field:
The utility model relates to a kind of mathematics angle square.
Background technology:
At present, the ruler that people use has meter ruler, ruler, set square, tape measure, tape measure, T-square etc., but the most function singleness of these rulers does not satisfy teaching and the needs of learning.
Summary of the invention:
The purpose of this utility model provides a kind of mathematics angle square, has possessed simultaneously the function of general ruler and protractor.
Above-mentioned purpose realizes by following technical scheme:
A kind of mathematics angle square, its composition comprises: main scale, described main scale one end is fixedly connected with the protractor at 180 ° of angles, the right-angle side of the protractor at the base of described main scale and described 180 ° of angles point-blank, the described main scale other end is fixedly connected with semicircle chi.
Beneficial effect:
The utility model is fixed together ruler and protractor, has possessed simultaneously the function of general ruler and protractor, can make the sizes model, is applicable to Students ' Learning and teachers' instruction.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
A kind of mathematics angle square, its composition comprises: main scale 1, described main scale one end is fixedly connected with the protractor 2 at 180 ° of angles, the right-angle side of the protractor at the base of described main scale and described 180 ° of angles point-blank, the described main scale other end is fixedly connected with semicircle chi 3.
Claims (1)
1. mathematics angle square, its composition comprises: main scale, it is characterized in that: described main scale one end is fixedly connected with the protractor at 180 ° of angles, the right-angle side of the protractor at the base of described main scale and described 180 ° of angles point-blank, the described main scale other end is fixedly connected with semicircle chi.
