figure b is a scaled copy of figure a.\nwhat is the scale factor from figure a to figure b?
figure b is a scaled copy of figure a.\nwhat is the scale factor from figure a to figure b?
Answer
Explanation:
Step1: Determine side lengths
Assume each grid square has side length 1. For Figure A (right triangle), let's find the length of a leg (vertical or horizontal). Suppose the vertical leg of Figure A is, say, 6 units (from grid count), and the vertical leg of Figure B is 2 units (from grid count).
Step2: Calculate scale factor
Scale factor is (\frac{\text{Length of Figure B}}{\text{Length of Figure A}}=\frac{2}{6}=\frac{1}{3}). (Alternatively, using horizontal leg or hypotenuse, the ratio remains same as it's a scaled copy.)
