Students - Compare similar sizes/angles of math shapes.

Have each student draw a shape (e.g. triangle) on blank paper, or open a PDF with shapes on it in Squid.  Use a ruler to measure the lengths of the sides, and a protractor to measure the angles.  Write these down.  Zoom in or out and measure again.  Are the different size shapes similar?  What is the ratio of side lengths?  Can you predict the length of a side based on this ratio?
