Answer

(x+1, y+2)

Answer

(x-2, y+1)

Question 9

Assuming that the lengths of the sides have congruent ratios, can the following be a dilation?

Accepted Answer

No, because the shapes are facing different directions

Answer

No, because the angles will not be congruent

Answer

Yes, because the triangles would meet all the requirements of dilations.

Answer

Yes, because the triangles would be congruent.
