A curved surface connects the base and the vertex.  cross section7cross section:ÖThe intersection of a solid and a plane. cylinder×!6cylinder:ÖA 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:ÖThe intersection of faces of a three-dimensional figure. face2face:ÖA flat surface, the side or base of a prism.  lateral area flateral area :ÖThe surface area of a cone, a cylinder, a prism, or a pyramid, not including the bases.  lateral face5lateral face:ÖOne side of a three-dimensional figure.  net4!jnet:ÖA two-dimensional representation of a three-dimensional figure that can be folded to form the figure.   perspectivepersceptive:ÖA point of view.  plane‘!Eplane:ÖA two-dimensional flat surface that extends in all directions.   polyhedron Opolyhedron:ÖA solid with four or more flat surfaces that are polygonal regions.  prism?!Œprism:ÖA polyhedron with two parallel, congruent faces called bases. A solid with the following characteristics: Ö1. Two faces, called the bases, are formed by congruent polygons that lie in parallel planes. Ö2. The faces that are not bases, called lateral faces, are formed by parallelograms. Ö3. The intersection of two adjacent lateral faces are called lateral edges and are parallel segments. pyramidœ!ºpyramid:ÖA 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: Ö1. All the faces, except one, intersect at a common point called the vertex. Ö2. The face that does not intersect at the vertex is called the base. The base is formed by a polygon. Ö3. The faces meeting at the vertex are called lateral faces. They are formed by triangles. regular pyramidŽregular pyramid:ÖA pyramid whose base is a regular polygon and in which the segment from the vertex to the center of the base is the altitude. similar solids Rsimilar solids:ÖSolids that have the same shape but not necessarily the same size.  slant heightâ!Gslant height:ÖThe altitude or height of each lateral face of a pyramid. solid@solid:ÖA three-dimensional figure formed by intersecting planes. sphereJ !fsphere:ÖThe set of all points in space that are a given distance from a given point, called the center. It has the following characteristics: Ö1. A radius is a segment whose endpoints are the center and a point on the sphere. Ö2. A chord is a segment whose endpoints are points on the sphere. Ö3. A diameter is a chord of the sphere that contains the center.  surface areaRsurface area:ÖThe sum of the areas of all the faces of a three-dimensional figure. vertex7vertex:ÖThe point where three or more planes intersect. volumeOvolume:ÖThe number of cubic units needed to fill the space occupied by a solid.8`?øÀÀ0 ÀÀ    @€
