Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
A cone
Nothing. Vertices is the plural term from vertex. A vertex is a point where two or more lines meet. They usually terminate (end) there but don't have to. In a 2- or 3-dimensional shape a vertex is a corner.
For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
A cone.
They are the points where three (or more) planes (or faces of the shape) meet.
Yes a cube has a vertex. In fact a cube has a total of 8 vertices and is a 3 dimensional shape.
A cone.
The 2-dimensional shape with one more vertex / side is a decagon.
vertex
The inside of a two dimensional shape is called the area.
the difference between a two dimensional shape and and a solid is that a two dimensional shape is plane and a solid you can see the whole shape a the inside.
