A transformation of a figure called the preimage changes the size, shape, or position of the figure to a new figure called the image.

Translations and reflections do not change the size or shape of a figure (e.g., the preimage and image are congruent figures). Translations and reflections change the position of a figure.

A translation is a transformation in which an image is formed by moving every point on the preimage the same distance in the same direction.

A reflection is a transformation in which an image is formed by reflecting the preimage over a line called the line of reflection. All corresponding points in the image and preimage are equidistant from the line of reflection.

The image of a polygon is the resulting polygon after the transformation. The preimage is the polygon before the transformation.

The result of first translating and then reflecting over the 𝑥- or 𝑦-axis may not result in the same transformation of reflecting over the 𝑥- or 𝑦-axis and then translating.

Sketch the image of a dilation of a right triangle or a rectangle limited to a scale factor of 1/4, 1/2, 2, 3, or 4. The center of the dilation will be the origin. (a)

The student will a) given a polygon, apply transformations, to include translations, reflections, and dilations, in the coordinate plane; and b) identify practical applications of transformations.

Translations and reflections maintain congruence between the preimage and image but change location. Dilations by a scale factor other than 1 produce an image that is not congruent to the preimage but is similar. Reflections change the orientation of the image.

A transformation of a figure, called preimage, changes the size, shape, and/or position of the figure to a new figure, called the image.
