Dilation - A transformation that enlarges or reduces a figure by a scale factor., Rotation - A transformation in which a figure is turned about a fixed point., Reflection - A transformation where a figure is flipped over a line. , Translation - A transformation that slides a figure from one position to another without turning., Transformation - An operation that maps a geometric figure, preimage, onto a new figure, image., Image - The resulting figure after a transformation., Preimage - The original figure before a transformation., Orientation - The direction the figure is facing., Congruence - Same shape, same size., Similar Figure - Same shape, not necessarily the same size, Translation (5 to the right and 2 down) - XY------------>X+5, Y-2, Reflection Across Y-Axis - XY------------> -X,Y, Reflection Across X-Axis - XY------------> X, -Y, Dilation (Enlargement) - XY------------> 2X,2Y, Rotation 90 CW - XY------------> Y, -X, Rotation 180 CW/CCW - XY------------> -X,-Y, Rotation 270 CW - XY------------> -Y, X, Dilation (Reduction) - XY------------> 0.5X,0.5Y, Scale Factor - ratio of distance of new figure to original figure from center of dilation, Translation (2 to the left and 5 up) - XY------------>X-2, Y+5,
