GLM3061  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. angle of rotationUangle of rotation:The degree measure of the angle through which a figure is rotated. complementary angles-!complementary angles:Two angles are complementary if the sum of their measures is 90. In the figure,1 and 2 are complementary 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. equiangular triangle!=equiangular triangle:A triangle with three congruent angles. equilateral triangle!aequilateral triangle:A triangle having all three sides congruent and all three angles congruent. exterior angles !nexterior angles:In the figure, tranversal t intersects lines l and m. 1, 2, 7, and 8 are exterior angles.  interior angles !pinterior angles:In the figure, transversal t intersects lines l and m. 3, 4, 5, and 6 are interior angles.  line of reflectionFline of reflection:The line a figure is flipped over in a reflection.  line of symmetry!bline of symmetry:A line that divides a figure into two halves that are reflections of each other.   line symmetryQline symmetry:Figures that match exactly when folded in half have line symmetry.  parallel linesq !Uparallel lines:Lines in the same plane that never intersect and have the same slope. perpendicular linesC0!aperpendicular lines:Lines which meet to form right angles and whose slopes have a product of -1. 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.  reflection#!Rreflection:A transformation in which a figure is flipped over a line of symmetry. regular polygon!Qregular polygon:A polygon that has all sides congruent and all angles congruent. rotational symmetry%!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. supplementary anglesZ(!Xsupplementary angles:Two angles are supplementary if the sum of their measures is 180. transformation_transformation:A mapping or movement of a geometric figure that changes its shape or position.  translation*!Itranslation:A transformation in which a figure is slid in any direction.  transversal !Ytransversal:A line that intersects two or more other lines to form eight or more angles. vertical angles6!vertical angles:Opposite angles formed by the intersection of two lines. In the figure, the vertical angles are 1 and 3, and 2 and 4.8`8( @  !@A@BpBD0@@Pp@@ @@  @ @a8bdPPP @8`0L0x`X @0 @  @@ @@@@@@@@@  4b|# }G8`p8`Xh@00 `` 00 ``  00 @   @00 `` 00 `` 00@Xh`p89`  ' @P@ P H@ @@  @!_ @ 8`@@ P  @@    @@@@   @@@@ !AA8`o @3Rd Rd$PRD$H+4RD$ B" @B P@C@#!E"B KU"bB5 @    f@@`@` ap ` P0 `0   0 *L(EF8`` ` @@       @@@@@@ @ e@` V% T$ `S  @ @UY%UUQ%@UM0 `8`0 0 0 0 8`@@   @@  @@~@ @  @   @@@  @@@  8`  ? ?????????????_/G#C!A @?@?`@3 @q08@(x@?'@ @ ??????????? 2 IHH08` `0@  0`C @    0 0 8`p~@ @    @ @@ @ @@@?@      @ @ @@@ 0@ 0 0 @@` @a8``0@  ` 8H@``@8` @``@Q9
