There is no simple answer to this question.
Polyhedra are named according to the number of faces that they have. An icosahedron is a 3-dimensional shape with 20 faces. It could be in the form of a pyramid with a 19-sided polygon as base. In that case, it has 20 vertices. Or it could be in the form of a prism with 18-sided polygons as base and in that case it has 36 vertices. There are several million different configurations, and the number of vertices varies.
The regular icosahedron is a Platonic solid with faces that are equilateral triangles. That has 12 vertices.

How many faces and vertices does a icosahedron have?
20 faces12 vertices
How many ventrices does regular icosahedron have?
Assuming 'ventrices' is actually supposed to be vertices, the plural of vertex (alternately the plural can be written as vertexes), then a regular icosahedron has 12 vertices.
How many edges does an Icosahedron have?
A Icosahedron has 20 faces and 30 edges.And for those of you who are wondering, it also has 12 vertices.30 edges
How many sides does an icosahedron have?
An icosahedron is a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles. icos is Greek for 20
Number of faces of an icosahedron or the number of vertices of a dodecahedron?
Twenty.
