An icosagon is a two-dimensional polygon, not a three-dimensional figure. An icosagon has 20 sides - while an icosahedron has 20 faces.
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
yes it is because its faces are pentagons so it is a polygon
An internal angle of the polygon.

Dodecahedron. <-- wrong a dodecahedron is a 3 dimensional shape having 12 faces. a 20-sided polygon is an icosagon
An icosagon is a two-dimensional polygon, not a three-dimensional figure. An icosagon has 20 sides - while an icosahedron has 20 faces.
an icosahedron (icosagon) is a regular polyhedron with 20 identical equilateral triangular faces
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
yes it is because its faces are pentagons so it is a polygon
Its a tetrahedron
you add up the areas of all the faces on the polygon.
An internal angle of the polygon.
Faces.

a cube
A square polygon by definition has one face and it is square.
