Transformations. There are four types –Translations –Reflections –Rotation –Dilation.
Term Transformation Describe The change in the position of a geometric figure, the pre-image, that produces a new figure called the image Representation.
An operation that moves or changes a geometric figure (a preimage) in some way to produce a new figure (an image). Congruence transformations – Changes.

Dilations Vocabulary Dilation: is a transformation that changes the SIZE, but not the shape of a figure. Scale Factor: tells how much larger or smaller the image of a dilation is than the preimage. remember this is the starting figure.

Dilation (x,y)  (kx, ky) (x,y)  (2x, 2y)

Dilation (x,y)  (kx, ky) (x,y)  (3x, 3y)

Dilation (x,y)  (kx, ky) (x,y)  (4x, 4y)
