Abstract
The utility model discloses a math teaching aid which comprises a right-angled triangular plate body. Length scale marks are formed on two right-angled sides of the right-angled triangular plate body, a level gauge is arranged on the right-angled triangular plate body, a protractor body is fixed to a sloping side of the right-angled triangular plate body, angle scale marks are formed on the protractor body, and a handle is further arranged on the protractor body. The math teaching aid has the advantages that the math teaching aid is simple in structure, standard horizontal lines and vertical lines can be conveniently drawn by observing the level gauge arranged on the right-angled triangular plate body, angles can be measured as the angle scale marks are formed on the protractor body fixed to the sloping side of the right-angled triangular plate body, lengths can be measured as the length scale marks are formed on the two right-angled sides of the right-angled triangular plate body, and the protractor body is convenient to hold as the handle is arranged on the protractor body.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of mathematics teaching aid.
Background technology
At present, in the mathematical education process, the teacher need draw a lot of horizontal lines and vertical curve at blackboard, owing to do not have special calibrator (-ter) unit, thereby can only go to judge by the mode of your range estimation, so the horizontal line of drawing and vertical curve are also nonstandard.
Summary of the invention
Problem to be solved in the utility model is: the mathematics teaching aid that a kind of drafting horizontal line simple in structure, convenient and vertical curve is provided and can takes measurement of an angle.
In order to address the above problem, mathematics teaching aid of the present utility model, comprise the right angle triangle body, be equipped with the length scale on two right-angle sides of described right angle triangle body, described right angle triangle body is provided with level meter, a protractor body is fixedly arranged on the hypotenuse of described right angle triangle body, and described protractor body is provided with angle index, also is provided with a handle on the described protractor body.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) be provided with the right angle triangle body, the right angle triangle body is provided with level meter, thereby by the eye-level instrument, can draw out comparatively horizontal line and the vertical curve of standard, and is very convenient; (3) a protractor body is fixedly arranged on the hypotenuse of right angle triangle body, the protractor body is provided with angle index, thereby can take measurement of an angle; (4) be equipped with the length scale on two of the right angle triangle body right-angle sides, thereby have the function of measuring length; (5) the protractor body is provided with a handle, is convenient to control.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, length scale, 2, the right angle triangle body, 3, level meter, 4, handle, 5, the protractor body, 6, angle index.
The specific embodiment
As shown in Figure 1, mathematics teaching aid of the present utility model, comprise right angle triangle body 2, be equipped with length scale 1 on two right-angle sides of described right angle triangle body 2, described right angle triangle body 2 is provided with level meter 3, a protractor body 5 is fixedly arranged on the hypotenuse of described right angle triangle body 2, and described protractor body 5 is provided with angle index 6, also is provided with a handle 4 on the described protractor body 6.
Mathematics teaching aid of the present utility model, simple in structure, be provided with right angle triangle body 2, right angle triangle body 2 is provided with level meter 3, thereby by eye-level instrument 3, can draw out comparatively horizontal line and the vertical curve of standard, and is very convenient.
A protractor body 5 is fixedly arranged on the hypotenuse of right angle triangle body 2, and protractor body 5 is provided with angle index 6, thereby can take measurement of an angle, and is equipped with length scale 1 on two right-angle sides of right angle triangle body 2, thereby has the function of measuring length.
Protractor body 5 is provided with a handle 4, is convenient to control.
