Pythagorean theorem teaching aid

Abstract

The invention discloses a teaching aid, and particularly discloses a Pythagorean theorem teaching aid which comprises a bottom plate, four congruent right triangle templates, a first square template and a second square template. An iron sheet is arranged in the bottom plate. The length of one leg of each right triangle template is a, the length of the other leg of each right triangle template is b, and the length of the hypotenuse is c. The length of each side of the first square template is a. The length of each side of the second square template is b. Magnets are arranged in the right triangle templates, the first square template and the second square template. According to the Pythagorean theorem teaching aid, the right triangle templates, the first square template and the second square template are demonstrated on the bottom plate so that students can know about and understand the Pythagorean theorem visually, the students can also splice the templates by themselves, so that the enthusiasm for learning of the students is stimulated, the creativeness of learning is improved, and meanwhile by demonstrating different proving processes, divergent thinking of the students can be improved, imagination of the students can be improved, and meanwhile the teaching aid is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a teaching aid for mathematics, in particular to a teaching aid for the Pythagorean theorem. Background technique [0002] In mathematics teaching, it is necessary to learn the properties of right triangles, among which the Pythagorean theorem is an important knowledge point, and there are many ways to prove the Pythagorean theorem. In the traditional teaching process, the teacher will draw pictures on the blackboard. Prove the Pythagorean theorem to students, but this teaching method is very boring, and it cannot show the proof of the Pythagorean theorem to students vividly, and it cannot inspire students' thinking and open their thinking. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and the technical problem to be solved is to provide a Pythagorean theorem teaching aid which is simple in structure, easy to use and capable of demonstrating multiple ways to prove the Pythagorea...
