Here we celebrate the power of algebra as a powerful way of finding unknown quantities by naming them, of expressing infinitely many relationships and connect ions clearly and succinctly, and of uncovering pattern and structure.
Triangular totaling. A tetrahedron is a 3-dimensional “triangle.” It has four faces, each a 2-dimensional triangle, and six edges. It turns out that a “triangle” in
(Sec Mindscape 16.) Compute the number of edges and the number of 2-dimensional faces there are in a 5-dimensional triangle.
