A dilation is a transformation in which an image is formed by enlarging or reducing the preimage proportionally by a scale factor from the center of dilation (limited to the origin in grade eight). A dilation of a figure and the original figure are similar. The center of dilation may or may not be on the preimage.
Sketch the image of a polygon that has been reflected over the 𝑥- or 𝑦-axis. (a)
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.
