Abstract
Combinational Mathematics chi disclosed by the invention, including the main scale and one end being made up of protractor and ruler is movably arranged on the checking scale of protractor center, and protractor is arranged on ruler downside.Simple structure of the present invention, it is easy to use, the efficiency and precision mapped in high school mathematics teaching activity are drastically increased, realize accurate reading at any angle and map, merging for chi and compasses is realized, for education activities are provided conveniently.
Description
Technical field
The present invention relates to a kind of high school mathematics teaching apparatus, particularly a kind of Combinational Mathematics chi.
Background technology
Math teacher is when teaching is given lessons; particularly when geometry and its related discipline is taught; the various aids including ruler, set square, protractor and compasses etc. would generally be used; these instruments are all separate; and unitary function; need continually to exchange when in use, carry using inconvenience, greatly have impact on drawing efficiency.
The content of the invention
Combinational Mathematics chi disclosed by the invention, simple structure is easy to use, realizes the multifunction of high school mathematics teaching chi and integrated, is drawn so as to facilitate teaching, improves drawing efficiency.
Combinational Mathematics chi disclosed by the invention, including the main scale and one end being made up of protractor and ruler is movably arranged on the checking scale of protractor center, and the protractor is arranged on ruler downside.Simple structure of the present invention, it is easy to use, quality connection is firm, it is easy to enter in maths teaching activities the drafting and demonstration of arc, the circle of line, angle, Along ent, bisector and special diameter etc., without frequently replacing different drawing tools, reduce the difficulty of drawing performance, realize accurate reading at any angle and draw system, the efficiency and precision mapped in high school mathematics teaching activity are drastically increased, merging for chi and compasses is realized, facilitated for education activities are provided.
A kind of improvement of Combinational Mathematics chi disclosed by the invention, the protractor is arranged on zero degree line and ruler the downside end face of one end of ruler and protractor on same straight line.This improvement by set protractor zero graduation line and ruler downside end face on the same line, to school high precision, be conducive to improving the precision and efficiency of camber line picture operation.
Combinational Mathematics chi disclosed by the invention, simple structure, it is easy to use, by the ruler, protractor and the slide calliper rule that set, the efficient accurate Drawing of the mathematical education regular pattern shape such as arc, circle of straight line, angle, Along ent, bisector and special diameter is realized, angle measures and draw high precision, while avoiding the frequent replacement in education activities between various teaching apparatus, so as to improve the convenience of education activities, several teaching and the difficulty drawn are reduced.
Brief description of the drawings
The structural representation of Fig. 1, Combinational Mathematics chi disclosed by the invention.
Reference numerals list：
1st, ruler；
2nd, protractor；
3rd, checking scale.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.It should be noted that the direction that the word "front", "rear" for being used in description below, "left", "right", "up" and "down" are referred in accompanying drawing, word " interior " and " outward " are referred respectively to towards or away from the direction of particular elements geometric center.
As shown in figure 1, Combinational Mathematics chi disclosed by the invention, including the main scale and one end being made up of protractor 2 and ruler 1 is movably arranged on the checking scale 3 of the center of protractor 2, the protractor 2 is arranged on the downside of ruler 1.Simple structure of the present invention, it is easy to use, quality connection is firm, it is easy to enter in maths teaching activities the drafting and demonstration of arc, the circle of line, angle, Along ent, bisector and special diameter etc., without frequently replacing different drawing tools, reduce the difficulty of drawing performance, realize accurate reading at any angle and draw system, the efficiency and precision mapped in high school mathematics teaching activity are drastically increased, merging for chi and compasses is realized, facilitated for education activities are provided.
A kind of improvement of Combinational Mathematics chi disclosed by the invention, the protractor 2 is arranged on the zero degree line and the downside end face of ruler 1 of one end of ruler 1 and protractor 2 on same straight line.This improvement by set protractor zero graduation line and ruler downside end face on the same line, to school high precision, be conducive to improving the precision and efficiency of camber line picture operation.
Combinational Mathematics chi disclosed by the invention, simple structure, it is easy to use, by the ruler, protractor and the slide calliper rule that set, the efficient accurate Drawing of the mathematical education regular pattern shape such as arc, circle of straight line, angle, Along ent, bisector and special diameter is realized, angle measures and draw high precision, while avoiding the frequent replacement in education activities between various teaching apparatus, so as to improve the convenience of education activities, several teaching and the difficulty drawn are reduced.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also including being combined constituted technical scheme by above technical characteristic.The above is specific embodiment of the invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications are also considered as protection scope of the present invention.
