100
The degree measure of the angle through which a figure is rotated
Angle of rotation
100
The line over which a figure is reflected
Line of reflection
200
The original figure before a transformation
Preimage
200
The resulting figure after a transformation
Image
200
The center point from which dilations are preformed
Center of dilation
200
A transformation that slides a figure from one position to another without turning
Translation
300
An operation that maps a geometric figure, preimage, onto a new figure, image
Transformation
300
A transformation theat enlarges or reduces a figure by a scale fator
Dilation
400
The fixed point around which shapes move in a circular motion to a new position
Center of rotation
400
Having the same measure; if one image can be obtained by another by a sequence of rotations, reflections, or translations
Congruent
400
A transformation in which a figure is turned about a fixed point
Rotation
500
A transformation where a figureis flipped over a line. Also called a flip.
Reflection
500
A type of symmetry a figure has if it can ve rotated less than 360 degrees about its center and still look like the original
Rotational symmetry
