The plane square is a special form of diamond, kite, parallelogram, polygon, quadrilateral, rectangle, rhombus or trapezoid.
You could add: tetragon.
You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
It is a cube which is 3D whereas the rest are 2D.
Draw a square of any size on a piece of paper, and that is what a 2D square looks like.
Yes. Just like a square is 2D.
It's a 2D shape.
A square.
Yes.
2D is a shape or an object that is flat and u can not pick it up, and it has 2 faces. 3D is a shape or an object that is a shape and you cant pick it up and hold it, and it can have as many faces.
In 2D, a square-based pyramid is represented as a square with a vertex pointing upwards, which could be referred to as a "triangle" in terms of its triangular sides and a "square" for its base. However, it doesn't have a specific name as a 2D shape since it's primarily a 3D object. The base is a square, and the triangular faces can be considered as simple triangles in a 2D context.
no. the square is 2d and the cube is 3d
A square!
