3D Geometry Polyhedrona 3-D solid made up of polygons Face Edge Vertex the flat surface of a polyhedron-- faces are all polygons the line segment formed when two faces meet the point where faces meet

Baseone face that determines the type of solid it is. (a polyhedro n is named by its base) Its base is a pentagon—there are two of them!

Types of Polyhedra Prismhas two bases that are parallel and congruent polygons, and the other faces are parallelograms (named by the base) rectangular prismpentagonal prism

Pyramidhas only one base (polygon) and the other faces are triangles Square pyramid—its base is a square

Other Types of Solids Cylinderhas two parallel bases that are congruent circles Conehas one base that is a circle and a vertex SphereAll points the same distance from a given point in 3-D

Surface Area (SA) the total area of all the (sur)faces of a 3-D figure *measured in square units This square pyramid has 5 faces: 4 congruent triangles and one square

Volume (V)the amount of space inside a 3-D figure **measured in units cubed Ex: m∙m∙m = m 3 V = bhH or lwh
