Abstract: The present invention provides a figure plate set for learning that comprises a first triangular plate (1) having an angle of 45°, an angle of 45°, and an angle of 90° and a second triangular plate (2) having an angle of 30°, an angle of 60°, and an angle of 90°. A length of one of two orthogonal sides (7, 8) of the first triangular plate (1) is same as a length of one of two orthogonal sides (14, 16) of the second triangular plate. A new triangular shape can be formed by combining the first triangular plate (1) and the second triangular plate (2).

Abstract: The present invention provides a figure plate set (10) for learning that comprises a first triangular plate (1) that has an isosceles triangular shape having an apex angle of 108° and base angles of 36°; and a second triangular plate (2) that has an isosceles triangular shape having an apex angle of 36° and base angles of 72°, wherein a length of isosceles sides (7, 8) of the first triangular plate (1) is same as a length of isosceles sides (14, 15) or a bottom side (16) of the second triangular plate (2), and a new triangular shape can be formed by combining the first triangular plate (1) and the second triangular plate (2).

Abstract: The present invention provides a figure plate set (10) for learning that comprises a plate member (4) having a concave portion (5); and groups of figure plates (1, 2, 3) that can form a regular polygon by being combined together, wherein the group of figure plates (1, 2, 3) can be stored on concave portion (5) in a state that the regular polygon is formed and the regular polygon is inscribed in an inner peripheral wall (6) of the concave portion (5). From the above, the user can experientially understand the regular polygon through the work of combining the figure plates. Thus, ability of geometric thinking about regular polygon is increased. In addition, since the plate member (4) has the concave portion (5), the group of figure plates (1, 2, 3) can be positioned. Thus, the figure plates (1, 2, 3) can be combined easily.
