If it is 3 dimensional it is an icosahedron If it is 2 dimensional it is an icosagon
Icosahedron.
Any of these shapes is practically circular. A 20-sided shape is an icosagon. a 50-sided shape is a pentacontagon (aka pentecontagon). A 100-sided shape is a hectogon (aka hecatontagon). A 1000-sided shape is a chiliagon.
A 20-sided flat figure (polygon) is called an icosagon. If it is a solid figure--three-dimensional--it is an icosahedron.
A 20-sided polyhedron is an icosahedron. A 20-sided polygon is an icosagon.
