The tetradecahedron has 14 faces that are congruent regular tetradecagons, which are polygons with 14 sides and 14 angles. There are also 28 edges in a tetradecahedron.
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.
