A vertex is the point where three or more edges of a solid figure meet.
A vertex on a cube, for example, is where any three edges meet. On a pyramid (square type) it could be at the point on the top or the 4 bottom edges. :)
a solid with flat sides meet at sharp edges and corners is called crystal structure
In a 3-dimensional shape with polygonal faces, an edge is a straight line at which two faces meet. A vertex is a point where three or more edges meet. In solid shapes which are not polyhedra, an edge is still a line - possibly curved - where two faces meet. But a vertex can be any corner, for example, the point of a cone.
Yes. I think of an edge as a line. The edges meet at vertices, and the faces meet at edges.
Vertex .
In solid geometry, a vertex is the point where three or more edges meet, so in your example there are NINE Vertices.
