In two similar geometric figures, the ratio of their corresponding sides is called the scale factor<span>. To find the </span>scale factor<span>, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the </span>scale factor<span> from one figure to the other. say a triangle had points of A(-1,0),B(0,1),and C(1,0) and the scale factor is two you basically double all the points so the A' is (-2,0), B' is (0,2), and C' is (2,0).</span>
