Building elements with matching side surfaces for fitting together to form constructions of varying shape, said building elements having the same length (L) and each having two opposite, equiform, flat, parallel end surfaces and at least three flat, rectangular side surfaces extending between said e
Building elements with matching side surfaces for fitting together to form constructions of varying shape, said building elements having the same length (L) and each having two opposite, equiform, flat, parallel end surfaces and at least three flat, rectangular side surfaces extending between said end surfaces to effect said matching of the side surfaces, the cross-sectional surfaces of the building elements each having a size which is a multiple of a triangular area of the size a 2/2, and the sides of the end surfaces having proportional lengths selected from the group a, a√ 2, 2a and 2a√a or a multiple thereof, "a" having a predetermined value, and the sides of the end surfaces defining proportional angles selected from the group 45°, 90°, 135° and 270°. The building elements are non-congruent and are nine in number divided into a first group of building elements with non-congruent cross-sectional surfaces consisting of a right-angled isosceles triangle, the equal sides each having a length a, a rectangle with sides a and 2a and a parallelogram with sides a√ 2 and 2a, a second group of building elements with non-congruent cross-sectional surfaces consisting of a right-angled isosceles triangle, the equal sides each having a length a√ 2, a parallel trapezium with sides a√ 2, 2a and 2a√ 2, and a symmetrical pentagon including with respect to the line of symmetry two parallel trapeziums having sides a, a√ 2, and a third group of building elements with non-congruent cross-sectional surfaces consisting of a right-angled isosceles triangle, the equal sides each having a length 2a, a symmetrical pentagon including with respect to the line of symmetry two parallel trapeziums having sides a√ 2 and 2a, and a symmetrical hexagon including with respect to the line of symmetry two parallelograms having sides a√ 2 and 2a, the end surfaces of the first group of building elements each having a height a, the end surfaces of the second group of building elements each having a height a√ 2 and the surfaces of the third group of building elements each having a height 2a.
