Oh, dude, a bangle is technically a 3D shape because it has thickness, like my jokes. It's not just a flat circle, it's got some depth to it, you know? So yeah, next time you're rocking that bangle, just remember it's living in a 3D world, just like us.
A television set is a 3D shape. The image (picture) on the television screen is a 2D shape. 3D is when it has length, width, and height. 2D is only length and width.
A piece of paper is 3D.
A nonagon is a 2D shape and there is not a 3D equivalent shape.
The suffix "hedron" implies 3D. The 2D suffix is "gon"
A rhombus is a four sided polygon, a quadrilateral. It is a 2d shape. 2d shapes have 2 dimensions, like length and width. 3d shapes have 3 dimensions, like length, width and depth.
A camera is a 3D shape. A photograph is a 2D projection of a 3D shape onto a 2D shape.
A television set is a 3D shape. The image (picture) on the television screen is a 2D shape. 3D is when it has length, width, and height. 2D is only length and width.
A square is a 2-dimensional shape. It has four lines, all of the same length. The opposite lines are parallel. All four angles are 90 degrees each.

a pyramid is a 3D shape :)
It's a 2D shape.
A sheet ( piece) of paper is a 3 - dimensional object. The length and width can be measured with a ruler. However, the thickness (3rd dimension) you will need a micrometer to measure the thickness. As a solid object it is a 'cuboid'.
