How many sides does a icosahedron have? 20 In geometry, a regular icosahedron (/ˌaɪkɒsəˈhiːdrən, -kə-, -koʊ-/ or /aɪˌkɒsəˈhiːdrən/) is a convex polyhedron with 20 faces, 30 edges and 12 vertices…. WebHow many faces, edges, and vertices are in a triangular pyramid? A triangular pyramid has 1 base and 3 three faces: total 4 triangles. Each edge is common to two triangles. Each vertex is common to three triangles. So it has 4 faces, 6 edges and 4 vertices. One of the vertices is the apex of the pyramid. 15 1 HsBadarinath
