Answer:
D. Congruent after dilation.
Step-by-step explanation:
From the figures, you can observe that the triangles don't have the same size or area, that means they cannot be congruent.
However, if we dilate the first triangle by a scale factor of 2, then both triangles will be congruent, because 5 x 2 = 10, 4 x 2 = 8 and 3 x 2 = 6.
Therefore, the right answer is D. Because if you dilate the first triangle, both would be congruent. Also, because they don't have the same area, size, and they aren't congruent.
