translation		a mirror image or result of a reflection
map		Repeats itself along a straight line
composition		when line of reflection is perpendicular bisector of segment BB'
tiling		a transformation does this to a figure onto its image
linesymmetry		dilation by a factor less than 1
preimage		transformation that uses circular motion
isometry		when an image is congruent to its preimage
reflection		when the image is enlarged or reduced
primenotation		when a half turn maps a figure onto itself
scalefactor		change in position, size or shape of a figure
image		a tessellation
symmetry		an isometry that maps a figure onto itself
dilation		original figure in a transformation
transformation		the result of a transformation
rotation		a repeating pattern of figures that completely covers a plane without overlap or gaps
friezepattern		more than one transformation at a time
reduction		composition of translation followed by reflection
glidereflection		used to identify image points
pointsymmetry		describes size change from preimage to image
tessellation		moves all points of a figure the same distance and direction
