ABSTRACT:
A set of generally flat, geometric figure building elements is disclosed, particularly (but not necessarily) for use in a geometric puzzle. The set combines an uneven number of pieces or elements, of which one type is square-shaped and the other types are right-angled isosceles triangles, one of which has the sides equal to the sides of the square pieces, while the other type is of the shape of right-angled triangles whose bases are of the same length as the sides of the square pieces. The puzzle produces advance in that it combines extreme simplicity of the pieces with the possibility of a wide variety of difficulty in assembling different shapes from the entire set. In a preferred embodiment, at least some of the pieces display a centrally located dot-like figure in one surface only thereof, to enable the creation of animal or man-like figures in which the dot presents representation of the eye, or to facilitate recognition of a particular piece in an overall shape to be solved.
