Problem 3.1

In class today we learned about how larger shapes are similar to the original shape. For example If the original shape was a parallelogram the first lager similar shape would be 4 times larger than the original shape, 4 units would have been used and the scale factor would be 2. A good thing to remember is that in similar shapes the side lengths and perimeter change by the scale factor. Area of the original times the scale factor squared gives the area of the new shape. The definition of scale factor is the number used to multiply the lengths of a figure to stretch or shrink it to a similar image. For example if the scale factor was 3 all the lengths of the new image would be 3 times larger than the original image.
