1 Students experimentally verify the properties related to the Fundamental Theorem of Similarity (FTS).
Theorem: Given a dilation with center 0 and scale factor r, then for any two points P and Q in the plane so that 0, P, and Q are not collinear, the lines PQ and P’Q’ are parallel, where P’ = dilation(P) and Q’ = dilation(Q), and furthermore, |P’Q’| = r|PQ|.
