In the figure, 1 and 2 are adjacent angles. alternate exterior angles3!alternate exterior angles:Nonadjacent exterior angles found on opposite sides of the transversal. In the figure, 1 and 7, 2 and 8 are alternate exterior angles. alternate interior angles 3!alternate interior angles:Nonadjacent interior angles found on opposite sides of the transversal. In the figure, 4 and 6, 3 and 5 are alternate interior angles.  altitude 6!~altitude:A line segment perpendicular to the base of a figure with endpoints on the base and on the vertex opposite the base. base{base:The base of a parallelogram or a triangle is any side of the figure. The bases of a trapeziod are the parallel sides. center of a circleb!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. center of rotationhcenter of rotation:It is a fixed point around which shapes move in a circular motion to a new position.  central angledcentral angle:An angle whose vertex is the center of a circle and whose sides intersect the circle.  chord4.!Vchord:A segment whose endpoints are on a circle. In the figure, vector JR is a chord.  circleb!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.  complementary angles8!complementary angles:Two angles are complementary if the sum of their measures is 90. In the figure, 1 and 2 are complementary angles.  composite figureAcomposite figure:A figure that is made up of two or more shapes.  congruent#congruent:Having the same measure. corresponding angles3!corresponding angles:Angles that have the same position on two different parallel lines cut by a transversal. In the figure, 1 and 5, 2 and 6, 3 and 7, and 4 and 8 are corresponding angles. corresponding partsFcorresponding parts:Parts of congruent or similar figures that match. diagonalMdiagonal:A line segment that joins two nonconsecutive vertices of a polygon. diameter!ndiameter:The distance across a circle through its center. In the figure, vector TG is a diameter of circle K. interior angle *interior angle:An angle inside a polygon. parallel linesz3!Xparallel lines:Lines in the same plane that never intersect and have the same slope.  perpendicular lines!eperpendicular lines:Lines which meet to form right angles and whose slopes have a product of -1.  polygon K&!Qpolygon:A simple closed figure in a plane formed by three or more line segments.  quadrilateral+quadrilateral:A polygon having four sides. radiusc;!Lradius:The distance from the center of a circle to any point on the circle. regular polygon0!Qregular polygon:A polygon that has all sides congruent and all angles congruent. rotation!!Lrotation:A transformation in which a figure is turned around a fixed point. rotational symmetryy!rotational symmetry:A figure that can be turned or rotated less than 360 about a fixed point so that the figure looks exactly as it did before being turned is said to have rotational symmetry. sector(!Qsector:A pie-shaped part of a circle bound by the radius of a circle and an arc. supplementary angles!Xsupplementary angles:Two angles are supplementary if the sum of their measures is 180.  tessellation+!Wtessellation:A repetitive pattern of polygons that fit together with no holes or gaps.  transversal3!Ltransversal:A line that intersects two parallel lines to form eight angles.  vertical angles >!vertical angles:Opposite angles formed by the intersection of two lines. In the figure, the vertical angles are 1 and 3, and 2 and 4.!  (pi) (pi):The ratio of the circumference of a circle to its diameter. The Greek letter represents this number.
