IM 7.1.5 Practice: The Size of the Scale Factor
Rectangles P, Q, R, and S are scaled copies of one another. Select all the pairs with a scale factor greater than 1.
Rectangles P, Q, R, and S are scaled copies of one another. Select all the pairs with a scale factor equal to 1.
Rectangles P, Q, R, and S are scaled copies of one another. Select all the pairs with a scale factor less than 1.
Triangle S and Triangle L are scaled copies of one another.
What is the scale factor from S to L?
What is the scale factor from L to S?
Triangle M is also a scaled copy of S. The scale factor from S to M is . What is the scale factor from M to S?
Are two squares with the same side lengths scaled copies of one another? Explain your reasoning.
Quadrilateral A has side lengths 2, 3, 5, and 6. Quadrilateral B has side lengths 4, 5, 8, and 10. Could one of the quadrilaterals be a scaled copy of the other? Explain.
Select all the ratios that are equivalent to the ratio .
