They are the sets of points (or lines) where two faces meet.
Cube or cuboid (3D figure) - 12 edges Dodecagon Deodeca (2D figure) Octahedron - (3D figure) - 8 faces 12 edges 6 vertices cube, rectangular, prism, pyramid
A cylinder.
They have sides but 3D figures have edges
A cube is a 3 dimensional figure that has 6 faces, 12 edges and 8 vertices
The Answer Is Cuboid For A 3D Figure Or A Dodecagon For 2D Figure. * * * * * Or it could be a hexagonal pyramid. Or a rectangular dipyramid.
The point where three or more edges of a 3D figure meet is called a vertex. In geometric terms, a vertex is a fundamental component of polyhedra and other solid figures, serving as a corner or a junction point for the edges. Each vertex can be connected to other vertices by edges, forming the overall shape of the solid.
A rhombohedron, a parallelepiped are two.
It means that the shape or a given figure has three or more edges meeting
A hexahedron. A parallelepiped, cuboid, quadrilateral frustum are examples.
a tetrahedron. it has four faces and six edges or vertices and four corner points
it can have 12 edges any 3d square can
The term "perimeter" typically applies to 2D shapes, referring to the total length of their boundaries. For 3D figures, a more appropriate term is "surface area" for the total area of the outer surfaces, and "volume" for the space enclosed. However, if you are looking for the "perimeter" in the context of a 3D figure, you can consider the perimeter of its base or edges by summing the lengths of all edges. For example, the perimeter of a cube is calculated by adding the lengths of all 12 edges.
