Scale Factors

Today in class we took some notes on scale facors. We found the shapes that were similar and then we found the difference between the similar figures. The rectangles that were similar were L, J, and N. The difference from L to J was 2, the difference of the area was 4. The difference from J to L was 1/2, the difference of the area was 1/4. The difference from L to N was 3, the difference of the area was 9. The difference from N to L was 1/3, the difference of the area was 1/9. the difference from J to N was 1 1/2 or 3/2. The difference from N to J was 2/3.
We also found the difference between triangles. The triangles that were similar were O, R, and S. The difference from O to R was 2, the difference of the area was 4. The difference from R to O was 1/2, the difference of the area was 1/4. The difference from O to S was 3, the difference of the area was 9. The difference from S to O was 1/3 the difference of the area was 1/9. Tghe difference from R to S was 1 1/2 or 3/2. The difference from S to R was 2/3.
