%0 Journal Article %T The Right Triangle as the Simplex in 2D Euclidean Space, Generalized to n Dimensions %A Istv¨¢n L¨¦n¨¢rt %J Journal of Applied Mathematics and Physics %P 2837-2850 %@ 2327-4379 %D 2022 %I Scientific Research Publishing %R 10.4236/jamp.2022.109189 %X The purpose of the research is to show that the general triangle can be replaced by the right-angled triangle as the 2D simplex, and this concept can be generalized to any higher dimensions. The main results are that such forms do exist in any dimensions; meet the requirements usually placed on an n-dimensional simplex; a hypotenuse and legs can be defined in these shapes; and a formula can be given to calculate the volume of the shape solely from the legs by a direct generalization of the Pythagorean Theorem, without computing the Cayley-Menger determinant. %K Cycles of Incidence %K Quadrirectangular Tetrahedron %K Rectangular Pentachoron %K Generalization of Pythagoras Theorem %K Volume of a Rectangular Simplex %K Cayley-Menger Determinant %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=120221
