An icosahedron is named after the number of faces that it has. The number of vertices will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with 18-gons as bases, will have 36 vertices. A pyramid with a 19-gon base will have 20 vertices. A bipyramid with a decagon base will have 12 vertices. There are very many more possible shapes.
A regular icosahedron has 20 faces (equilateral triangles), 30 edges and 12 vertices.

In an icosahedron, five faces meet at each vertex. The icosahedron is a polyhedron with 20 triangular faces, and its symmetrical structure allows for this arrangement, contributing to its overall geometric properties. Each vertex connects three edges and forms angles that accommodate the five surrounding triangular faces.
An icosahedron is a 20-sided figure. It also has 30 edges.
