In the figure, R is a point of symmetry.   reflection!Rreflection:A transformation in which a figure is flipped over a line of symmetry.  regular tessellation !}regular tessellation:A tessellation in which only one shape is used to form the pattern and that shape is a regular polygon.   resultant*resultant:The sum of two or more vectors.  rotation}!Lrotation:A transformation in which a figure is turned around a fixed point. 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. scalar*scalar:A constant multiplied by a vector. semi-regular tessellationN !semi-regular tessellation:A tessellation formed using combinations of two or three different regular polygons with the same pattern of polygons at each vertex.  tessellationWtessellation:A repetitive pattern of polygons that fit together with no holes or gaps.  translation !Itranslation:A transformation in which a figure is slid in any direction. uniform tessellationsiuniform tessellations:Tessellations containing the same arrangement of shapes and angles at each vertex. vectorevector:A directed segment representing a quantity that has both magnitude, or length, and direction.8`@ "@A?@A "@@        @@ "@A?@A "@@        @@ "@A?@A "@@        @@ "@A?D$(A(jJf&U )HL$@Ui)HHJ$@#UĨfV@8`p~@ @    @ @@ @ @@@?@      @ @ @@@ 0@ 0 0 @@` @a8`@@   @@  @@~@ @  @   @@@  @@@  8`X4FA@@0@@@` @0@@@` @@p@H@p@H0@H@@a @0@ys?s<@@0@a @@@0@@@@@` @@@0@` @@@0@AFX48`  ? ?????????????_/G#C!A @?@?`@3 @q08@(x@?'@ @ ??????????? 2 IHH08````DD $ $@@  @@``  b``8`  2` &`0 ! `@  pd0L! 2a C&@@ @ 2a C&d0L! p@  pd0L! 2a C&@@ @ 2a C&d0L! p@  pd0L! 2a C&@@ @ 2a C&d0L! p@  pd0L! 2a C&@@  `@0a Cd0Lp@@ $* F#RU#0LiJBd%%*HJBBQ%%*Ff%C4 8`` ` @@       @@@@@@ @ e@` V% T$ `S  @ @UY%UUQ%@UM0 `
