A quadrilateral has the following coordinates.

Question

E (4,7) ; F (7,5) ; G (8,14) ; H (5,9)

Quadrilateral EFGH is transformed and the coordinates of the new figure are shown below.

E' (12,21); F' (21, 15) ;G' (24,42); H' (15,27)

Is the transformation a dilation?
A.
No, because point H'(15 , 27) is incorrect.

B.
No, because point G'(24 , 42) is incorrect.

C.
Yes, because all points were multiplied by a scale factor of 8.

D.
Yes, because all points were multiplied by a scale factor of 3.

Answer 1
