it a triangle as a 2d shape
No, it is a 3D shape.
The 2D version of a triangular prism is a triangle. A triangular prism consists of two triangular bases and three rectangular faces connecting the corresponding sides of the triangles. In two dimensions, only the triangular bases are represented, without the depth that defines the prism in three dimensions. Thus, the focus is solely on the shape of the triangle itself.
A triangular prism has two triangular faces, a rectangular prism does not have any.
A triangular prism has a triangular cross-section. A rectangular prism has a rectangular cross-section.
A triangular prism.
No, it is a 3D shape.
a triangle is 2D whereas a triangular prism is 3D.
It is a triangular prism.
A triangular prism can have a square or triangular base.
A triangular prism has a triangle and a rectangular prism doesn't.
A triangular prism has two triangular faces, a rectangular prism does not have any.
You cannot have a 2d prism. The 2d cross section will depend on the plane of the cross section.
A triangular prism.
A triangular prism has a triangular cross-section. A rectangular prism has a rectangular cross-section.
A triangular prism has triangular bases, a heagonal prism has ... you guessed it! ... hexagonal bases.
Oh, dude, a triangular prism in 2D is called a triangle. It's like a triangle, but missing that extra dimension to make it a prism. So yeah, just a good old triangle in flatland.
A triangular prism is a 3-d object. It does not have a 2-d name because it is not a 2-d object!
