Today in class students worked to understand that the angles in scaled copies have the same measure as the original figure.
Answers to HW: 1. B, C, D, and F 2. Since the lengths of AC and BD are 6, and AC corresponds to PR.....the scale factor must be 1/2. Since QS corresponds to BD....QS must also be 3 units long. 3. a. 6 units b. 3 units c. 3 because distances between points in Figure 2 are 3 times the corresponding distances in Figure 1 d. 3 units because the scale factor is 3 4. You could use 12 cups of pink paint to 10 cups of blue paint to make 2 batches OR 18 cups of pink paint to 15 cups of blue paint to make three batches.
