the degree measure of the angle through which a figure is rotated
angle of rotation
having the same measure; if one image can be obtained by another by a sequence of rotations, reflections, or translation
congruent
the line over which is reflected
line of reflection
a transformation in which a figure is turned about a fixed point
rotation
a transformation that slides a figure from one position to another without turning
translation
the center point from which dilations are performed
center of dilation
a transformation that enlarges or reduces a figure by a scale factor
dilation
the original figure before a transformation
preimage
a type of symmetry a figure has if it can be rotated less than 360 degrees about its center and still look like the original
rotational symmetry
the line over which is reflected
line of reflection
a fixed point around which shapes move in a circular motion to a new position
center of rotation
the resulting figure after a transformation
image
a transformation where a figure is flipped over a light. also called a flip
reflection
an operation that maps a geometric figure, preimage, onto a new figure, image.
