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.
Yes a triangle is a 2D polygon shape
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.
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
