A first order approximation treatment of the case where a repair is made of the central portion of a vibrating isotropic plate of regular polygonal shape using a material of circularly anisotropic constitutive characteristics ...

This research presents a proposal of contextualizing Geometry teaching, for Elementary School (stag e II) students, exploring the concepts of regular polygons. First of all, some theoretical concepts about the subject ...

The tiling technique consists of filling the plane with geometric figures without overlapping or empty spaces. Although this technique is quite old, the science is recent and contains aspects that have not yet been developed ...
