Abstract
The utility model relates to a geometrical figure teaching ruler, which comprises a bottom ruler 3 which is provided with scales. The utility model is characterized in that the geometrical figure teaching ruler also comprises a plurality of nodes of straight rulers 2 with the scales, the nodes of the straight rulers are composed of a plurality of straight rulers 2, both ends of each straight ruler 2 are provided with small holes and a head and a tail among each straight ruler 2 are superposed and are movably connected through hinges 1. The bottom ruler 3 is sheathed with a ruler sheath 4 which is correspondingly and glidingly connected with the bottom ruler 3. The head end of a straight ruler on the head end of the nodes of the straight rulers is movably connected with the bottom ruler 3 through the hinges 1, and the end of a straight ruler on the end of the nodes of the straight rulers is movably connected to the ruler sheath 4 through the hinges. The utility model can be used for forming various geometric figures and visually and dynamically demonstrating relations among figures and rim angles of the geometric figures. The geometrical figure teaching ruler has convenient operation, can excite the learning passion of students and can enhance the learning interest of the students. Consequently, teaching quality is enhanced.
Description
Technical field
The utility model relates to a kind of geometry teaching apparatus, relates in particular to a kind of geometric figure teaching chi.
Background technology
At present, in the teaching process of plane geometry, teacher mainly be to use set square with corresponding diagram plots on blackboard, then by analyzing, contrast, concluding, sum up to student explain.Use set square mapping teaching to have the following disadvantages: 1, set square carries inconvenience; 2, mapping trouble, and only diagram plots on blackboard, lack intuitive and stereoscopic sensation, can not excite student's learning enthusiasm and enthusiasm; 3, the corner of various figures relation can not be intuitively, dynamically show.
Summary of the invention
The utility model purpose provides a kind of geometric figure teaching chi that can intuitively, dynamically demonstrate various plane geometric figures.
For achieving the above object, the technical solution adopted in the utility model is: a kind of geometric figure teaching chi, comprise: the end chi that has scale, it is characterized in that: also comprise the multiple-level ruler that has scale, multiple-level ruler is made up of a plurality of rulers, the two ends of each ruler all have aperture, and head and the tail are overlapping and flexibly connect by hinge between each ruler; Be with the chi cover on the end chi, and the chi cover becomes relative being slidingly connected with end chi; The head end and the end chi of the head end ruler of multiple-level ruler flexibly connect by hinge, and the end of the terminal ruler of multiple-level ruler is movably connected in chi by hinge and puts.
The utility model can be by multiple-level ruler the distortion of each ruler and the displacement of terminal ruler on end chi of multiple-level ruler, form various geometric figures, can intuitively, dynamically demonstrate the relation between the geometric figure, between the corner, easy to use, can excite student's learning enthusiasm, strengthen students'interest in learning, thereby improve the quality of teaching.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
A kind of geometric figure teaching chi comprises end chi 3 that has scale and the multiple-level ruler 2 that has scale, and multiple-level ruler is made up of a plurality of rulers 2, and the two ends of each ruler 2 all have aperture, and head and the tail are overlapping and by hinge 1 flexible connection between each ruler 2; Be with chi cover 4 on the end chi 3, and chi cover 4 and 3 one-tenth relative being slidingly connected of end chi; The head end of first section ruler of multiple-level ruler and end chi 3 flexibly connect by hinge 1, and the end of the latter end ruler of multiple-level ruler is movably connected on the chi cover 4 by hinge.The length of end chi 3 is generally longer than the length that other respectively save ruler, is convenient to be combined into multiple geometric figure like this.
