Step-by-step explanation:

First, we notice that ΔΝΑΤ is greater than ΔHPW, so there was a dilation, the factor of dilation can be calculated comparing the length of corresponding sides of the triangles. So, if we compare NT with HW, we get:


(NT)/(HW)=(3)/(2)=1.5

Therefore, the first transformation was a dilation by a factor of 1.5.

So, with this transformation, the coordinates of the original triangle will be equal to:

(x, y) ----------> (1.5x, 1.5y)

H(-6, -4) -----> (1.5(-6), 1.5(-4)) = (-9, -6)

P(2, -6) ------> (1.5(2), 1.5(-6)) = (3, -9)

W(-6, -6) ----> (1.5(-6), 1.5(-6)) = (-9, -9)

Then, the transformation is a rotation of 180° about the origin because the rule that these coordinates follow are:

(x, y) ------> ( -x, -y)

(-9, -6) ----> N(9, 6)

(3, -9) ------> A(-3, 9)

(-9, -9) -----> T(9, 9)

Therefore, the answer is:

C. D1.5 a
