Abstract
The utility model discloses a geometry teaching ruler; one end of a bottom ruler with scales is movably connected with a multi-joint straight ruler through a hinge; the tail end of the multi-joint straight ruler is movably connected with a ruler sleeve on the other end of the bottom ruler through the hinge; and the ruler sleeve and the bottom ruler are relatively connected in a sliding way. Through the design, the deformation of a plurality of straight rulers of the multi-joint straight ruler and the sliding of the ruler sleeve on the bottom ruler, various geometric shapes can be formed so as to directly and dynamically present the relationship among various geometric shapes, facilitate convenient use, arouse the learning enthusiasm of students, improve the learning interest of the students so as to improve the teaching quality.
Description
Technical field
The utility model designs a kind of geometry teaching apparatus, is a kind of several teaching chi specifically.
Background technology
In geometry teaching, the teacher mainly uses set square and ruler on blackboard figure to be drawn, then by analyzing contrast to student explain, lack intuitive and third dimension, can not be intuitively, dynamically expression, can not excite student's learning enthusiasm and enthusiasm, set square and ruler carry inconvenience, and the mapping trouble.
Summary of the invention
The purpose of this utility model is that a kind of several teaching chi that may intuitively, dynamically demonstrate plane geometric figure is provided.
To achieve these goals, the utility model end of chi at the bottom of having scale is connected with multiple-level ruler by hinge, and the end of multiple-level ruler flexibly connects by hinge with the chi cover that is enclosed within the other end of end chi, and the chi cover becomes relative being slidingly connected with end chi.
By above setting, the utility model is by the distortion of each ruler of multiple-level ruler, and chi is enclosed within the slip on the end chi, can form various geometric figures, can intuitively, dynamically demonstrate the relation between the various geometric figures, easy to use, can excite student's learning enthusiasm, strengthen students'interest in learning, thereby improve the quality of teaching.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Among the figure 1, end chi 2, hinge 3, ruler 4, chi cover
The specific embodiment
As shown in Figure 1, the utility model end of chi 1 at the bottom of having scale is connected with multiple-level ruler 3 by hinge 2, and the end of multiple-level ruler 3 flexibly connects chi cover 4 and 1 one-tenth relative being slidingly connected of end chi with the chi cover 4 of the other end that is enclosed within end chi 1 by hinge.By above setting, the distortion of each ruler by multiple-level ruler 3, and the slip of chi cover 4 on end chi 1, can form various geometric figures, can intuitively, dynamically demonstrate the relation between the various geometric figures, easy to use, can excite student's learning enthusiasm, strengthen students'interest in learning, thereby improve the quality of teaching.
