That's pretty impossible if you ask me , but go to Google images and type in two sided shape. See what pops up.Septagon or Heptagon = seven sided shape
A five-sided 2-dimensional shape is a pentagon.
5 sided 2-dimensional object
Hemisphere.
Any quadrilateral (4-sided shape) has 2 diagonals.
A one-sided shape is called a "monogon," which is a theoretical concept representing a shape with one side and one vertex. A two-sided shape is called a "digon," which is also a theoretical concept representing a shape with two sides and two vertices. In geometry, these shapes are considered degenerate cases and do not exist in the physical world.
It's called a monogon. 2 sided shape is digon like semi=circle. Alright this is getting chaos.
Septagon or Heptagon = seven sided shape
A five-sided 2-dimensional shape is a pentagon.
An octagon is an 8 sided 2 dimensional shape. A cylinder with the base of a hexagon (6 sided shape) would be an 8 sided 3 dimensional shape.
A 2 sided shape is called a digon
Biagon
10 sided 2D shape is called a decagon 20 sided 2D shape is called a icosagon 30 sided 2D shape is a swimming pool 40 sided 2D shape is unknown 50 sided 2D shape is unknown 60 sided 2d shape is unknown 70 sided 2d shape is unknown 80 sided 2d shape is unknown 90 sided 2d shape is unknown 100 sided 2d shape is unknown 110 sided 2d shape is unknown 111 sided 2d shape is unknown 120 sided 2d shape is unknown 130 sided 2d shape is unknown
A two dimensional 10 sided shape is a decagon.
Parallelogram
A 5-sided 2-dimensional figure is a pentagon and a 5-sided 3-dimensional shape is a pentahedron.
