    In geometry, a 20-sided geometric figure is called a Icosagon. The interior angle of a regular icosagon is 162°. The sum of any icosagon's interior angles is 3240 degrees. ((A Dodecahedron is a polyhedron with twelve faces)).

    I always knew it as a duodecagon but I see from the rest of the answers I must be wrong, or am I?

    I knew the answer but would not have had a hope in hell of spelling it, but the two people at the top are right.
