info@snapandsolve.comTo find the scale factor of the dilation, compare the lengths of corresponding sides of triangles D'E'F' and DEF. For example, measure the length of D'E' and DE. The scale factor is the ratio of D'E' to DE.
From the graph, D'E' is 4 units and DE is 8 units. Therefore, the scale factor is 4/8 = 1/2.
