Characteristics of a solid A three dimensional (3D) object that has one or more curved or plane faces. Has a length, width and height. Polyhedron Round surface A solid bounded by polygons (ex:cube) Having at least one curved surface (sphere, cone, cylinder) Prism a solid having equal and parallel sides. The base serves to identify its name Pyramid Square based pyramid Triangular based pyramid a solid made up of a base and triangular shaped faces that converge to a vertex. Nets Face : each of the surfaces of a polyhedron Edge : Line formed by the meeting of two surfaces Vertex : A point common to at least three or more edges (a corner) Net : A way of presenting, in 2D, all faces of a polyhedron.
