GLGE031  alternate exterior angles!alternate exterior angles:In the figure, transversal t intersects lines l and m. 1 and 7, and 2 and 8 are alternate exterior angles. alternate interior angles!alternate interior angles:In the figure, transversal t intersects lines l and m. 3 and 5, and 4 and 6 are alternate interior angles. consecutive interior anglesu!consecutive interior angles:In the figure, transversal t intersects lines l and m. 3 and 6, and 4 and 5 are consecutive interior angles. corresponding angles !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. parallel lines!Uparallel lines:Lines in the same plane that never intersect and have the same slope. parallel planesF!Uparallel planes:Planes that do not intersect. In the figure, plane PQR || plane JKL. point-slope formpoint-slope form:An equation of the form y - y1 = m(x - x1), where m is the slope and (x1, y1) is a given point on a nonvertical line. rate of change3rate of change:The change in a quantity over time.   skew lines]!nskew lines:Two nonparallel lines that do not intersect. In the figure, seg. AX and seg. BC are skew segments.  slope/!slope:The ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line.  slope-intercept formislope-intercept form:An equation of the form y = mx + b, where m is the slope and b is the y-intercept.   transversal !Ytransversal:A line that intersects two or more other lines to form eight or more angles.8` @ !!A @  @@\yy @@ ` @C `` 0PH x H HP8`8( @  !@A@BpBD0@@Pp@@ @@  @ @a8bdPPP @8`8( @  !@A@BpBD0@@Pp@@ @@  @ @a8bdPPP @8``8$8$`$  @!Aqa?
