Summary
[edit]DescriptionHexaedro Leonardiano Especial.jpg |
Español: La cuarta estelación del hexaedro está representada por un poliedro presentado en dos formas diferentes, las cuales son el Hexaedro Leonardiano Especial y el Hexaedro Leonardiano ampliado.
Antes de mostrar la cuarta Estelación del hexaedro, fabricaremos una pirámide cuadrada semis hueca de Jose. Primero elegimos una pirámides cuadrada de Johnson cuyas arista midan 3 Cm, luego preparamos 4 triángulos escaleno, cuyo primer cateto mide 2 Cm, el segundo cateto mide 3 Cm y la unión de ambos catetos forman un ángulo de 120 grados. La medida del otro cateto la dejo como tarea. Procedemos a unir un triángulo escaleno en cada una de las aristas de las caras laterales que poseen el ápice principal como punto común. El resultado es una pirámide cuadrada Semis Hueca de Jose = JL2, La JL2, posee 12 caras interiores y una cara cuadrada intermedia, en total 13 caras. Existen infinitas pirámides semis huecas de Jose y son nombradas de acuerdo al polígono de la base ejemplo: Pirámides triangular semis hueca de Jose = JL1, pirámide pentagonal semis huecas de Jose = JL5, etc. Ahora procedemos a construir el Hexaedro Leonardiano Especial: elegimos un hexaedro regular convexo cuyas aristas midan 3Cm, y 6 pirámide cuadrada Semis huecas de Leonardo cuyas base cuadradas midan 3Cm de lado. Procedemos a unir las 6 JL2 en cada una de las 6 caras poliédricas del hexaedro regular, y tendremos como resultado un Hexaedro Leonardiano Especial. El hexaedro Leonardiano especial posee 72 caras interiores. tiene 24 aristas exteriores, 72 aristas interiores, y 12 aristas intermedias, para un total de 108 aristas. Además ostenta 6 vértices exteriores, 24 vértices interiores y 8 vértices intermedios para un total de 38 vértices. El conjunto de vértices exteriores del hexaedro Leonardiano ampliado, forma un octaedro regular imaginario. El conjunto de vértices exteriores del hexaedro Leonardiano especial, forma un octaedro regular imaginario, observemos: El Hexaedro estrellado Leonardiano y El Hexaedro estrellado Leonardiano ampliado fueron idealizados el 10 de mayo del 2010 por el dominicano, Jose Joel Leonardo |
