We have a final study guide for our geometry class and we never learned anything about scale factor so we were just wondering if anyone could help explain any of the questions. One of the people in our group said that it's just the measure of the side of one shape over the side of the other shape inside, since the shapes we're given are all shapes with equal sides, so the proportions between the inside and outside shapes would be the same. Any help would be appreciated, thanks.
