"base of a three-dimensional figureRbase of a three-dimensional figure:The faces on the top and bottom of the figure. center of a circle^!center of a circle:The given point from which all points on a circle are the same distance. In the figure,P is the center of the circle. chord!Ochord:A segment whose endpoints are on a circle. In the figure, JR isa chord. circle^!icircle:The set of all points in a plane that are the same distance from a given point called the center.  circumference,circumference:The distance around a circle. composite figureCcomposite figure:A figure that is made up of two or more shapes.  composite solidDcomposite solid:An object made up of more than one type of solid.   cone!!zcone:A three-dimensional figure with one circular base and one vertex. A curved surface connects the base and the vertex.  coplanar!coplanar:Points or lines that lie in the same plane. In the plane M, points A, B, and C are coplanar, and AB and BC are coplanar.  cylinder0$!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.  diagonal_1!fdiagonal:A segment joining two nonconsecutive vertices of a polygon. In the figure, SQ is a diagonal.  diameter&!ldiameter:The distance across a circle through its center. In the figure, seg. TG is a diameter of circle K. edge>edge:The intersection of faces of a three-dimensional figure. #face of a three- dimensional figureTface of athree- dimensional figure:The flat surface of a three-dimensional figure. lateral face of a prism3lateral face of a prism:A face that is not a base. lateral surface areaOlateral surface area:The sum of the areas of the lateral faces of a pyramid.  netv)!jnet:A two-dimensional representation of a three-dimensional figure that can be folded to form the figure. pipi:The ratio of the circumference of a circle to its diameter. The Greek letter represents this number. The value of pi is 3.1415926... . Approximations for pi are 3.14 and 22/7 . 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. prismG!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. radius!Lradius:The distance from the center of a circle to any point on the circle. regular pyramidregular pyramid:A 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 solidsRsimilar solids:Solids that have the same shape but not necessarily the same size.  skew lines.!dskew lines:Two nonparallel lines that do not intersect. In the figure, AX and BC are skew segments.  slant heightGslant height:The altitude or height of each lateral face of a pyramid. solid@solid:A three-dimensional figure formed by intersecting planes.  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`00HP xHH  @@ @@@@ā @@@@ 8`x0@   @@  p>H>p>@@  @@    @0x8`80@00@@@@ P`  a @   < <  I >%)J %)I "2 @@@@00@088`o @3Rd Rd$PRD$H+4RD$ B" @B P@C@#!E"B KU"bB5 @    f@@`@` ap ` P0 `0   0 *L(EF8`
