WebIn geometry, the truncated tetrahedron is an Archimedean solid. It has 4 regular hexagonal faces, 4 equilateral triangle faces, 12 vertices and 18 edges (of two types). It can be constructed by truncating all 4 vertices of … WebEdges of a tetrahedron. In general terms, we can consider the edges as the line segments that join two vertices. In total, a tetrahedron has 6 edges. We can also define edges as the line segments where two triangular faces of the tetrahedron meet. The edges are located at the limits of the tetrahedron.
