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
