A curved surface connects the base and the vertex. cylinder*!6cylinder:A solid figure whose bases are formed by congruent circles in parallel planes and whose lateral surface is curved. The segment whose endpoints are the centers of the circular bases is called the axis of the cylinder. The altitude is a segment perpendicular to the bases with an endpoint in each base. edge>edge:The intersection of faces of a three-dimensional figure. #face of a three- dimensional figureSface of a three-dimensional figure:The flat surface of a three-dimensional figure.  lateral areaelateral area:The surface area of a cone, a cylinder, a prism, or a pyramid, not including the bases. lateral face of a prism3lateral face of a prism:A face that is not a base. net !jnet:A two-dimensional representation of a three-dimensional figure that can be folded to form the figure.  plane!Eplane:A two-dimensional flat surface that extends in all directions.   polyhedronOpolyhedron:A solid with four or more flat surfaces that are polygonal regions.  prism!prism:A polyhedron with two parallel, congruent faces called bases. A solid with the following characteristics:1. Two faces, called the bases, are formed by congruent polygons that lie in parallel planes.2. The faces that are not bases, called lateral faces, are formed by parallelograms.3. The intersection of two adjacent lateral faces are called lateral edges and are parallel segments.  pyramid!pyramid:A solid figure that has a polygon for a base and triangles for sides. A pyramid is named for the shape of its base. A solid with the following characteristics:1. All the faces, except one, intersect at a common point called the vertex.2. The face that does not intersect at the vertex is called the base. The base is formed by a polygon.3. The faces meeting at the vertex are called lateral faces. They are formed by triangles.  similar solidsRsimilar solids:Solids that have the same shape but not necessarily the same size.  slant heightGslant height:The altitude or height of each lateral face of a pyramid. solid@solid:A three-dimensional figure formed by intersecting planes. sphereA!csphere:The set of all points in space that are a given distance from a given point, called the center. It has the following characteristics:1. A radius is a segment whose endpoints are the center and a point on the sphere.2. A chord is a segment whose endpoints are points on the sphere.3. A diameter is a chord of the sphere that contains the center.  surface areaRsurface area:The sum of the areas of all the faces of a three-dimensional figure. vertex of a prismBvertex of a prism:The point where three or more planes intersect. volumeOvolume:The number of cubic units needed to fill the space occupied by a solid.8``@6@  8P %H@IH0$ xI2P)     @b  @8@  @ 6@@8b`D2 XJTJT1J8`?0     @
