Transformation – An operation that moves or changes a geometric figure in some way to produce a new figure.
Pre-Image – the original figure in a transformation.
Pre-Figure –the original figure in a transformation.
Prime Notation – the apostrophe attached to a symbol to indicate a transformation.
Rigid – transformations that move a figure to a new place without altering its shape and size.
Non-rigid – transformations that move a figure to a new place and may alter the shape or size.
Rotation – a transformations in which every point of a figure moves along a circular path around a fixed point.

3. Introduction to Geometry – Transformations and Constructions Vocab
Translation – A transformation in which a geometric figure is moved to another location without any change in size or orientation.
Dilation – a transformation that changes a figures size, but its shape orientation and location remain the same.
Reflection – a transformation in which each point of a figure has an image that is the same distance from the line of reflection as the original figure.
Center of dilation – the fixed point about which the figure is enlarged or reduced.
Scale Factor – the ratio of a side length of the image to the corresponding side length of the original figure.

Clockwise – movement in the same direction that a clock moves.
Counterclockwise – movement in the opposite direction that a clock moves.
Enlargement – the increase the size of an object with dilation.
Reduction – to decrease the size of an object with dilation.
Geometric Construction – To draw a shape, line or angle accurately using a compass and straightedge (ruler).
Compass - A tool used to draw circles at a given radius.
Bisector – a point, line, or plane that intersects a line or angle at the midpoint.
Perpendicular bisector - a point, line, or plane that intersects a line or angle at the midpoint forming a right angle.
