In the figure,P is the center of the circle. 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 figurefcomposite figure:made of triangles, quadrilaterals, semicircles, and other two-dimensional figures.  coneZ!zcone:A three-dimensional figure with one circular base and one vertex. A curved surface connects the base and the vertex. cylinderq!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. 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.  height of a parallelogram!gheight of a parallelogram:The shortest distance from the base of a parallelogram to its opposite side.  lateral face of a prism3lateral face of a prism:A face that is not a base.  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 . 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. pyramidC"!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. rectangular prism'!|rectangular prism:A solid figure that has two pairs of parallel opposite faces and congruent bases that are all rectangles. sector2sector:a region of a circle bounded by two radii.  semicircleMsemicircle:Congruent arcs whose endpoints lie on the diameter of the circle. solid@solid:A three-dimensional figure formed by intersecting planes. sphere!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. three-dimensional figureAthree-dimensional figure:A figure that encloses a part of space. triangular prism4triangular prism:a prism that has triangular bases. 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`?0     @H>p>@@  @@    @0x8`@@    @@@    @@@x  ` `  88` @@@ 0@p?8`80@00@@@@ P`  a @   < <  I >%)J %)I "2 @@@@00@088` 0 @!"$@@  @@@  `@@ @ @G @ 0 8`o @3Rd Rd$PRD$H+4RD$ B" @B P@C@#!E"B KU"bB5 @    f@@`@` ap ` P0 `0   0 *L(EF8`
