Suppose you have a pair of similar triangles and and are corresponding sides. If AB = 5 and the scale factor is 4, what is EF? Select one: a. 9 b. 5 c. 20 d. 4
Since the scale factor, or ratio, is 1:4, and there are no other answers that make sense: side AB must Equal c, as 5 x 4 = 20. More information please.
