  3. 12-1&2 Three-Dimensional Figures and Nets A net is a two-dimensional pattern that you can fold to form a three-dimensional figure. faces A polyhedron is a three-dimensional figure whose surfaces are polygons. The polygons are the faces of the polyhedron. An edge is a segment that is the intersection of two faces. A vertex is a point where edges intersect. edge vertex

  4. 12-3&4 Surface Areas of Prisms and Cylinders A prism is a polyhedron with two congruent, parallel bases. The other faces are lateral faces. A prism is named for the shape of its bases. An altitude of a prism is a perpendicular segment that joins the planes of the bases. The heighth of the prism is the length of an altitude. Like a prism, a cylinder has two congruent parallel bases. The bases of a cylinder are circles. An altitude of a cylinder is a perpendicular segment that joins the planes of the bases. The heighth of a cylinder is the length of an altitude.
