Today in class, we learned about the scale factor inside bigger shapes like triangles. We figured out a strategy to make perfect smaller shapes. First look at each side of the shape. Find the halfway point and make a dot. Do this for every side of the shape. Now connect the dots from each point so your lines make a smaller version of the original shape. The scale factor would be a fraction, because you are dividing the shape large to small. This would've been dividing the number too, but since the scale factor doesn't work in division, the factor would be less than 1. The area of the new perimeter is the scale factor times the original area squared. Example: the original area=2 and the scale factor from the original to the new is 3. 3 squared is 9, so the new area of the shape is 18. 2•(3^2)= 18.
