8.3(A) generalize that the ratio of corresponding sides of similar shapes are proportional, including a shape and its dilation
8.3(B) compare and contrast the attributes of a shape and its dilation(s) on a coordinate plane
8.3(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
8.8(D) use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle‐angle criterion for similarity of triangles
8.10(A) generalize the properties of orientation and congruence of rotations, reflections, translations, and dilations of two‐dimensional shapes on a coordinate plane
8.10(B) differentiate between transformations that preserve congruence and those that do not
8.10(C) explain the effect of translations, reflections over the x‐ or y‐axis, and rotations limited to 90°, 180°, 270°, and 360° as applied to two‐dimensional shapes on a coordinate plane using an algebraic representation
Translation
Reflection
Rotation
8.10(D) model the effect on linear and area measurements of dilated two‐dimensional shapes
