100

a non-rigid transformation in which the pre-image and image of a figure are similar

dilation

100

a correspondence between a figure and a slide image of the figure

translation

100

The original figure, before it has been transformed

Preimage

100

a figure in a plane has _______   ________ if the figure can be mapped onto itself by a rotation of 180 degrees or less

rotational symmetry

200

a rigid transformation in which a figure is turned about a fixed point

rotation

200

a type of transformation in which the size or shape, or both the size and shape, of the preimage changes

non-rigid transformation

200

A tiling of a plane with figures that leave no gaps or overlaps

tesselation

200

a figure in a plane has a _____ __ _____ if the figure can be mapped onto itself by a reflection in the line

line of symmetry

300
a rigid transformation in which a figure flips over a given line
reflection
300

Size changes, congruence transformations, and combinations of these are ______ transformations

similarity 

300

the new figure which has been transformed using a motion-rule on each point of the image

image

300

two objects are ______ if they have the same shape, or one has the same shape as the mirror image of the other. (More precisely, one can be obtained from the other by uniformly scaling, possibly with additional translation, rotation and reflection.)

similar

400

a transformation in which the preimage maps onto a congruent image

rigid transformation

400

a rigid transformation that preserves length, angle measure, parallel lines, and distance between points

isometry (or congruence transformation)

400

the operation that maps the preimage onto the image

transformation

400
