Would a dilation result in a figure that is similar? Why or Why not?

Yes, because a dilation scales a figure by a factor of k, making a proportional shape, just a different size.

No, because a dilation scales a figure by a factor of k, making it a different size which means they cannot be similar.

No because dilations do not change the size or shape of the figure, which means they are congruent.

Yes, because dilations do not change the size or shape of the figure, which means they are similar.
