Geometry
a function that moves or changes a figure in some way to produce a new figure
transformation
a combination of two or more transformations
composition of transformations
the point about which a figure is rotated
center of rotation
a figure resulting from a transformation
image
A transformation that "flips" a figure over a mirror or reflection line.
reflection
the number of degrees a figure rotates
angle of rotation
the original figure in a transformation
preimage
the line over which a figure is reflected
line of reflection
a transformation that shifts or slides every point of a figure or graph the same distance in the same direction
translation
a transformation involving a translation followed by a reflection
glide reflection
A transformation that preserves distance and angle measures
rigid motion
A transformation in which a figure is turned around a point
rotation
