Learning goals: Learning Goals Assessed • Describe characteristics of scaled copies using informal and formal language. (Lesson 1) • Explain that scale factor is the number multiplied by each length in an original figure to create a scaled copy.  (Lesson 2) • Explain the proportional relationship between lengths in a figure and corresponding lengths in a scaled copy. (Lesson 2) • Explain that corresponding angles in a figure and its scaled copies have the same measure. (Lesson 3) • Draw a scaled copy of a figure using a given scale factor. (Lesson 3) • Describe how scale factors greater than `1`, less than `1`, or equal to `1` affect corresponding distances in scaled copies. (Lesson 4) • Understand and explain how the scale factor between figure `A` and figure `B` relates to the scale factor between figure `B` and figure `A`. (Lesson 4) • Understand and explain how scaling lengths impacts the area of a scaled copy. (Lesson 5)
