Moreover, due to manual operation, it is easy for the placed figures to be deformed, and students need to use their imagination, and the corresponding knowledge points are not intuitive.

[0024] Embodiment 1

[0025] See also Figure 1 , Figure 3 to Figure 4 A teaching model for educational purposes, comprising a triangular bottom plate 1 and a triangular top plate 7, the shapes of the triangular bottom plate 1 and the triangular top plate 7 can be an isosceles triangle, a right-angled isosceles triangle or an equilateral triangle, the height of the triangular top plate 7 is equal to half of the height of the triangular bottom plate 1, so that when the triangular top plate 7 rotates with point A as the base point, the areas of the formed triangles ABD and ACE are always equal, the triangular bottom plate 1 and the triangular top plate 7 are both provided with intersection holes 2 at the same inflection point, the triangular bottom plate 1 is provided with symmetrical fixing holes 3 at the other two inflection points, and the triangular top plate 7 is provided with symmetrical fixing holes 3 at the other two inflection points.

[0026] See also Figure 1 , Figure 5 A threaded tube 14 is fixedly sleeved in the intersection hole 2 on the triangular bottom plate 1, and a bolt 15 is threadedly sleeved in the threaded tube 14. The screw rod of the bolt 15 passes through the intersection hole 2 on the triangular top plate 7, and the bottom end of the head of the bolt 15 is pressed on the end of the triangular top plate 7 away from the triangular bottom plate 1, so that the operator can press the triangular top plate 7 against the triangular bottom plate 1 by twisting the bolt 15 forward, so that the triangular top plate 7 can remain fixed in position after being rotated to a specific position. When the triangular top plate 7 needs to be rotated, the bolt 15 can be twisted in the reverse direction so that the triangular top plate 7 is no longer tightly attached to the triangular bottom plate 1 and can be movable.

[0027] See also Figure 1 to Figure 2 , Figure 6 A rubber band is arranged between the triangular bottom plate 1 and the triangular top plate 7, and the rubber band is divided into an inclined section Ⅰ11, a parallel section 12 and an inclined section Ⅱ13. One end of the inclined section Ⅰ11 is fixedly sleeved in one of the fixing holes 3 of the triangular bottom plate 1, and the other end is movably sleeved in the fixing hole 3 on the same side of the triangular top plate 7. The two ends of the parallel section 12 are respectively sleeved in the two fixing holes 3 on the triangular top plate 7. One end of the inclined section Ⅱ13 is fixedly sleeved in another fixing hole 3 of the triangular bottom plate 1, and the other end is movably sleeved in the fixing hole 3 on the triangular top plate 7 is in the fixing holes 3 on the same side, so that when the triangular top plate 7 rotates with the intersection hole 2 as the base point, the positions of the two fixing holes 3 on the triangular top plate 7 will change, while the positions of the two fixing holes 3 on the triangular bottom plate 1 will not change. At this time, the triangular top plate 7 will pull the inclined section Ⅰ11 and the inclined section Ⅱ13 of the rubber band to deform, so that the inclined section Ⅰ11 can form a triangle with the auxiliary line Ⅱ5 and the auxiliary line Ⅴ9, and the inclined section Ⅱ13 can form a triangle with the auxiliary line Ⅲ6 and the auxiliary line Ⅵ10.

[0028] See also Figure 3 to Figure 4 , Figure 6 The intersection hole 2 on the triangular bottom plate 1 is marked as point A, and the two fixing holes 3 are marked as points B and C respectively. The intersection hole 2 on the triangular top plate 7 is marked as point A, and the two fixing holes 3 are marked as points D and E respectively.

[0029] See also Figure 1 , Figure 3 to Figure 4 , Figure 6 An auxiliary line Ⅰ4 is set between the BC points on the triangle bottom plate 1, an auxiliary line Ⅱ5 is set between the AB points, an auxiliary line Ⅲ6 is set between the AC points, an auxiliary line Ⅳ8 is set between the DE points on the triangle top plate 7, an auxiliary line Ⅴ9 is set between the AD points, and an auxiliary line Ⅵ9 is set between the AE points. By combining different auxiliary lines, multiple groups of triangles can be formed to improve the teaching quality.
