A 2D shape with 3,000,000 sides is called a myriagon. The prefix "myria-" denotes 10,000, so a myriagon has 10,000 sides. In geometric terms, a myriagon is a polygon with 3,000,000 sides, each of equal length and internal angles adding up to 180 degrees. It is a very rare and complex shape in mathematics.
A ten-sided 2D polygon is known as a decagon.
A nonagon is a 2D shape and there is not a 3D equivalent 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.
If you look down from the top, it is circular. From the bottom, it is circular. From the side, it is a triangle.
As a 2D polygon shape it is an 8 sided octagon.
Dodecagon is the name for the regular 12 sided polygon, meaning that all its side lengths and angles are the same. Not sure if there is a name for a general 12 sided 2d shape.
QUADRILATERAL its spelled right.
A 2D shape with 9 sides is called a Nonagon.
No. A 2d shape is a plane area, which may be regarded as a face, which is bounded by a side or sides.
a trapezoid
They both have a face, not a :) face but a side of a shape is called a face and a 2d and 3d shape both show a face of the shape
Octagon
2D shapes include squares, triangles, rectangles and circles.
