The invention relates to the technical field of a teaching appliance, and provides a triangle corner property demonstrator. The triangle corner property demonstrator comprises a fixed ruler, a movable inner ruler and a movable outer ruler, the fixed ruler comprises a first support plate and a second support plate, a groove is formed between the first support plate and the second support plate, and the first support plate is provided with a first scale area; the movable inner ruler is hinged to the first support plate and the second support plate through pins, the movable inner ruler is provided with a second scale area, and the scale starting point of the first scale area is corresponding to the scale starting point of the second scale area; the other end of the movable inner ruler is connected with the movable outer ruler, the movable outer ruler is provided with a third scale area, and the third scale area is opposite to the second scale area; and the other end of the movable outer ruler is fixed in the groove through a positioning mechanism. According to the invention, the corner properties of a triangle can be demonstrated for students through the triangle corner property demonstrator. The triangle corner property demonstrator can enable the students to quite easily accept content related with triangle corner relations, and at the same time, can also raise students learning interest and enhance the mathematics hand-brain practicing capabilities of the students.
Description
technical field [0001] The invention belongs to the technical field of teaching aids, in particular to a device for demonstrating the properties of triangle corners. Background technique [0002] In the teaching process of mathematics, classroom teaching aids are indispensable auxiliary tools, including rulers, triangular rulers, protractors, compasses and other collection demonstration instruments. [0003] Among them, the learning content of the triangle nature in the mathematics geometry part of junior high school is more critical. This part is the basic content for building students' geometric thinking and is the key link for learning other content in the subsequent geometry part. Abstract and not easy to understand and learn, for example: [0004] (1) The stability of the triangle; [0005] (2) The relationship between the three sides of a triangle, that is, the sum of the two sides is greater than the third side, and the difference between the two sides is smaller th...
