The triangle whose vertices are 3,-1, 2,4, and 5,1 is transformed by the rule (x,y) ----> (2x, 5y). Is the image similar or congruent to the original figure?

Question

The triangle whose vertices are 3,-1, 2,4, and 5,1 is transformed by the rule (x,y) ----> (2x, 5y). Is the image similar or congruent to the original figure?

A. The image is congruent to the original triangle.
B. The image is similar but not congruent to the original triangle.
C. The image is neither similar not congruent to the original triangle.

Answer 1

if the images are similar, then all the side lengths are in the same ratio.

after the transformation, this is clearly not so.
So, C

Answer 2

You are correct, my mistake. The image is neither similar nor congruent to the original triangle. Thank you for pointing that out.
