(3)  Proportionality. The student applies mathematical process standards to use proportional relationships to describe dilations. The student is expected to:

(A)  generalize that the ratio of corresponding sides of similar shapes are proportional, including a shape and its dilation;

(B)  compare and contrast the attributes of a shape and its dilation(s) on a coordinate plane; and

(C)  use an algebraic representation to explain the effect of a given positive rational scale factor applied to two-dimensional figures on a coordinate plane with the origin as the center of dilation.
