Jeremy wants to verify that the transformation shown is a dilation. he finds the lengths of segments qa and ad to be 4 units. point q is the center of dilation. triangle a b c is dilated to create triangle d e f. the length of q a is 4 and the length of a d is 4. to verify that the transformation is a dilation, jeremy should also check which of the following? select three options. qb = one-halfqe qc = cf de = 2ab ac = one-halfef if bc = 2.25, then ef = 2.25
