It is a 3 dimensional shape
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
It is NEITHER. A SQUARE is a PLAIN 2-dimensional figure . A PRISM & a PYRAMID are 3-dimensional objects.
The 2D polygon that has 11 vertices would be called an 11-gon. As for 3Dfigures, there are too many to name. One would be a decagon-based pyramid.
No. A pyramid is a three-dimensional shape.
A square based pyramid is a 3-d object. It does not have a 2-d name!

a 2d square * * * * * A square has four sides. A side is not a face. A tetrahedron (triangular pyramid) has four faces.

No. A pyramid is a three-dimensional shape.
Pentagon 2d shape is a pentagon 3d object is a pyramid.
A prism is 3d and a pyramid is in 2d
