Description
Technical field
Teaching aid technical field is the utility model is related to, is specially that one kind is used for the dismantled and assembled set square of mathematical education.
Background technology
Mathematics is a relatively more abstract subject, in the teaching of mathematics.Mathematics teacher generally will when being given lessons
The educational aids such as protractor, ruler and set square are carried and use, protractor, ruler and the set square of prior art are all each
All it is semicircle for the protractor used at present from independent individual, also needs to carry out simply when angle is more than 180 degree
Mathematical computations, complexity is added, and need during mathematical education that these utensils are continually used alternatingly, increased
The workload of mathematics teacher, it is not convenient enough especially to carry, or even can occur to omit down wherein one attending class because being eager, more
Effect of giving lessons on classroom can be adversely affected.
Utility model content
The purpose of this utility model is to be directed to problem above, there is provided one kind is used for the dismantled and assembled set square of mathematical education, its energy
The circular drafting of special diameter is enough carried out, measures 0-360 degree angular dimensions, its is simple in construction, and cost is low, uses and carries and be all non-
It is often convenient.
To realize object above, the technical solution adopted in the utility model is：It includes set square main body（1）, its feature
It is, the set square main body（1）For equilateral right angled triangle, it is provided with its surface along symmetrical two of right angle bisector
Equilateral right angled triangle（12）Groove, and it is provided with linearly aligned manhole along right angle bisector（11）, the triangle
Chi main body（1）Right angle is equipped with protractor（2）；The protractor（2）Inside is provided with chute, set square main body（1）It is embedded in cunning
At groove, and 360 degree of rotations can be carried out.
Further, the set square main body（1）, protractor（2）And equilateral right angled triangle（12）It is equipped with scale.
Further, the manhole（11）It is linearly aligned according to scale rule.
Further, the set square main body（1）And protractor（2）For transparent plastics material.
The beneficial effects of the utility model：The utility model provides one kind and is used for the dismantled and assembled set square of mathematical education, its energy
The circular drafting of special diameter is enough carried out, measures 0-360 degree angular dimensions, its is simple in construction, and cost is low, uses and carries and be all non-
It is often convenient.
1st, the set square main body rotated around protractor, it is easy to draw angle straight line.
2nd, manhole can carry out particular circle drafting.
3rd, the utility model generally transparent material, it is easy to observe and measure angle.

Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality
Be described in detail with new, the description of this part be only it is exemplary and explanatory, should not be to the scope of protection of the utility model
There is any restriction effect.
As Figure 1-Figure 4, concrete structure of the present utility model is：One kind is used for the dismantled and assembled set square of mathematical education, it
Including set square main body 1, it is characterised in that the set square main body 1 is equilateral right angled triangle, is provided with its surface along right angle
Two symmetrical equilateral grooves of right angled triangle 12 of bisector, and it is provided with linearly aligned circle along right angle bisector
Through hole 11, the right angle of set square main body 1 are equipped with protractor 2；The inside of protractor 2 is provided with chute, and set square main body 1 is inlayed
At chute, and 360 degree of rotations can be carried out.
Preferably, the set square main body 1, protractor 2 and equilateral right angled triangle 12 are equipped with scale.
Preferably, the manhole 11 is linearly aligned according to scale rule.
Preferably, the set square main body 1 and protractor 2 are transparent plastics material.
Specifically used, bowlder is drawn, protractor 2 is pressed against on blackboard, by being caught in chalk at manhole 11,
Draw and justify around protractor 2；When measuring angle, protractor 2 is pinned, rotates set square main body 1 at required groove, is drawn out straight
Line；Set square can directly be used by drawing straight line.
It should be noted that herein, term " comprising ", "comprising" or its any other variant are intended to non-row
His property includes, so that process, method, article or equipment including a series of elements not only include those key elements, and
And also include the other element being not expressly set out, or also include for this process, method, article or equipment institute inherently
Key element.
Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Illustrate that being only intended to help understands method and its core concept of the present utility model.Described above is only of the present utility model preferred
