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).
Claims9
A figure plate set for learning, comprising:
- a first triangular plate having angles of 45°, 45° and 90°;
- and
- a second triangular plate having angles of 30°, 60° and 90°, wherein
- a length of one of two orthogonal sides of the first triangular plate is same as a length of one of two orthogonal sides of the second triangular plate,
- a new triangular shape can be formed by combining the first triangular plate and the second triangular plate,
- a group of figure plates is further provided so that an outer shape of the group of figure plates matches the new triangular shape when the group of figure plates is combined, and
- when the group of figure plates is combined so that the outer shape of the group of figure plates matches the new triangular shape, a point of contact of apexes of all or a part of the group of figure plates matches a circumcenter of the new triangular shape.
