Stretching and Shrinking Final Exam

OBJECTIVE: • To recognize similar figures in the real world • To find a missing measurement in a pair of similar figures [5.1.1] • To apply what has been learned about similar figures to solve real-world problems[1.1.4] • To collect data, analyze it, and draw reasoned conclusions from it[3.3.3] ACTIVITIES/ASSESSMENT:

Exam part: Draw (using a ruler and other equipment as necessary) a figure. This figure must have sides that are different lengths and all angles must be different. Draw a second similar figure that must have a scale factor that is NOT one of the following numbers: 1/2 (0.5), 1, 2, 3, 4, or 5. An example of a scale factor that could be used is 1.5(1-1/2) or 0.75(3/4). Cut them out. Demonstrate why the two shapes are similar. A data sheet may accompany the two shapes
