Answer:

D. reflection across a vertical line

Step-by-step explanation:

Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.

It is not a vertical translation; this means that the triangle shifted up or down.

It is not a horizontal translation, this means that the triangle shifted left or right.

It is not a rotation about point A either, this would have meant that the triangle spun around.

average = $\frac{26+2+4}{4}$ = $\frac{32}{4}$ = 8
