An icosahedron is in fact not a polygon at all, but a polyhedron. As a polyhedron it is regular however.
The regular icosahedron is one of only five possible regular polyhedra. It has 20 faces, each of which is an equilateral triangle.

How many different types of semiregular tessellations are there?
There are eight different types of semiregular tessellations. Also called Archimedean tessellations, they occur when two or more convex regular polygons form tessellations of the plane in a way each polygon vertex is surrounded by the same polygons and in the same order.
What do you call a polygon or shape that has 20 sides?
A icosahedron.
20 sided shape?
Icosahedron is a 20 sided polygon.
What is a 20 sided shape called?
Regular 20 sided solid is an icosahedron, so a plane equivalent is presumably an icosagon?
Which one of the following sets of regular polygons can be used for a semiregular tessellation?
See the answer below.
Is a truncated isocahedron a regular polyhedron?
No. It is a semi-regular polyhedron. Explanation. The truncated icosahedron is a polyhedron that can be constructed from an icosahedron with the 12 vertices truncated (cut off) such that one third of each edge is cut off at each of both ends. This creates 12 new pentagon faces, and leaves the original 20 triangle faces as regular hexagons A regular polyhedron is a polyhedron whose faces are congruent regular polygons. The truncated icosahedron is NOT a regular polyhedron, it is a semiregular polyhedron. It is a uniform polyhedron.
What is the name of an 20 sided polygon?
an icosahedron (icosagon) is a regular polyhedron with 20 identical equilateral triangular faces

Are Uniform tessellations are semiregular?
By the use of wording "uniform" you are in fact stating that the tesselations are "regular"

What is the face shape of an icosahedron?
In geometry, an icosahedron is a regular polyhedron with 20 identical equilateral triangular faces.
Is a hexagon a regular polygon or not a regular polygon?
A 6 sided hexagon polygon can be regular or irregular.
What is A polygon that is not regular?
its a not regular polygon
