Prisms and Cylinders • • • Prisms and cylinders have 2 congruent parallel bases.

Prisms and Cylinders • • • Prisms and cylinders have 2 congruent parallel bases. A lateral face is not a base. The edges of the base are called base edges. A lateral edge is not an edge of a base. The lateral faces of a right prism are all rectangles. An oblique prism has at least one nonrectangular lateral face.

An altitude of a prism or cylinder is a perpendicular segment joining the planes

An altitude of a prism or cylinder is a perpendicular segment joining the planes of the bases. The height of a three-dimensional figure is the length of an altitude. Surface area is the total area of all faces of a threedimensional figure. The lateral area of a prism is the sum of the areas of the lateral faces.

Cylinders • The lateral surface of a cylinder is the curved surface that connects

Cylinders • The lateral surface of a cylinder is the curved surface that connects the two bases. • The axis of a cylinder is the segment with endpoints at the centers of the bases. • The axis of a right cylinder is perpendicular to its bases. • The axis of an oblique cylinder is not perpendicular to its bases. • The altitude of a right cylinder is the same length as the axis.
