It is a face of the 3-d figure.
You're probably thinking of a cone. There is some disagreement as to whether the point of a cone qualifies as a vertex.
There is no 3 dimensional figure with JUST 3 edges.
no it is a 4 dimensional figure not a 3 dimensional figure * * * * * No. A quadrilateral is a two dimensional figure. It has a length and a breadth and no more.
A sphere.
Sphere
A cuboid and a pyramid for examples.
A polyhedron.
A Shelf, A Tv, And A Floor Maybe ? Those are some 2 dimensional but its okay. Theres also a Rectangular and Triangular Prisms.
An ellipsoid or a toroid or other 3-dimensional objects with more than one "holes". Or simply a ... sphere.
Yes a sphere can be considered to be a curved plane 3 dimensional figure.
Well it matters if you put it in a 3-dimensional or a 2-dimensional figure because if you turn it into a 3-dimensional figure the the surface would have a flat surface with volume and area.If you draw a quad in 2-D then the figure you draw is the surface.
Both are 3-dimensional figures wiith a curved surface.
The surface.The surface.The surface.The surface.
Surface area concerns a 3-dimensional figure such as a cube or sphere. Area concerns a 2-dimensional figure such as a square or circle.
A curved surface is like imagining a sheet of paper that is bent or a flag waving in the wind. A curved edge is like an elastic stick bent in one(C curve) or more points(S curve). The curved surface beeing 3 dimensional(3D) and the curved edge 2 dimensional(2D) unlike the simple surface and edge which are 2D respectively 1D.
A face is a flat surface of a 3 dimensional figure.
