Solid figures can be classified by the
number of faces, edges, and vertices.
what the arrow is pointing to.
A polygon that is a flat surface of a solid
figure is a face.
An edge is a line segment formed where
two faces meet.
A vertex is a point where three or more
edges meet. The plural of vertex is
vertices.
