Polyhedron
Prism
a polyhedron that has two congruent polygons for bases and other faces that are all rectangles
Cylinder
a solid figure that has 2 parallel bases that are congruent circles
Cone
a solid figure that has a flat, circular base and one vertex
Sphere
a solid figure whose curved surface is the same distance from the center to all its points
Pyramid
a solid figure with a polygon base and all other faces are triangles that meet at a common vertex
Polyhedron
a solid figure with faces that are polygons
Lateral face
any surface of a polyhedron other than a base
Non-polyhedron
some 3-dimensional figures have curved surfaces, these figures are NOT polyhedrons
Edge
the line segment made where 2 faces of a solid figure meet
Vertex
the point where 2 or more rays meet; the point of intersection of 2 sides of a polygon; the point of intersection of 3 (or more) edges of a solid figure; the top point of a cone; the plural of vertex is vertices
