Students should use their previous knowledge about two-dimensional shapes and their attributes from previous grade levels to identify corresponding sides and corresponding congruent angles of similar figures. Students should be able to express the relationships between the lengths of corresponding sides of similar figures using proportions.
7.5 Proportionality. The student applies mathematical process standards to use geometry to describe or solve problems involving proportional relationships. The student is expected to:
(A) generalize the critical attributes of similarity, including ratios within and between similar shapes
