1. A pentagon is a polygon with five sides and five angles.
2. Pentagon A fivesided building near Washington DC, containing the US Department of Defense and the offices of theUS Armed Forces.
A pentagon is a 5 sided polygon whose 5 interior angles add up to 540 degrees.
There are multiple 3-d pentagon shapes. One such is the Dodecahedron, it has 30 edges and 20 vertices. Another 3-d pentagon shape is the pentagonal prism.
A pentagon has 5 sides. A base in Baseball has 5 sides. A two dimensional stick figure house has five sides.
Well, a 3D model or shape means a 3D (looks real) house or tree or even a cube or a sphere. Paper is flat, so things on it are two dimensional (2D). If you change the appearance of a square into a cube by adding extra lines, or a circle into a sphere by clever shading, you're making it look three dimensional (3D). Two dimensional figures have width and length; 3D figures also have height or depth.

I'm assuming you mean a 3-d shape with faces of pentagons. This is called a Dodecahedron
A 3-d shape made from pentagonal faces is a dodecahedron (12 sides).
