Question 4 (5 points)

A triangle has the vertices A(–7, 8), B(1, –7), and C(7, 6). After a dilation, the vertices of the image are A’(–28, 32), B’(4, –28), and C’(28, 24). What is the scale factor of the dilation?

Question 4 options:

	4
	8
	2

Question 5 (5 points)

Determine if the two figures are similar by using transformations.

Question 5 options:

	The figures are similar because a reflection followed by a dilation will map figure ABCD onto figure MNPQ.
	The figures are similar because a rotation followed by a dilation will map figure ABCD onto figure MNPQ.
	The figures are similar because a translation followed by a dilation will map figure ABCD onto figure MNPQ.
	The figures are not similar. The ratios of the side lengths are not equal.
