yes at least 1 face
2d shapes only have length and width, while 3d shapes have length, width and depth.
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons.
Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have 'faces'.
A dodecahedron is a polyhedron with between 18 and 30 faces.
A net is a 2D representation of a 3D shape
1. both of them have hight and width
yes at least 1 face
a 2d shape can only ever contain 1 face!
Give vidoes to understand the 2d and 3d shapes clearly
2d shapes only have length and width, while 3d shapes have length, width and depth.
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
I think they all have 1.... because 2d shapes are flat!!! :)
The difference between 2d and 3d shapes is that, a 2d shape is flat, has no volume and depth and cannot be handled while a 3d shape can be held, has depth, volume and can hold things inside it. These are the dimensional shapes which are mostly used in geometry.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons.
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
