If a polygon is dilated by a scale factor of 3 then the original polygon and its image are congruent?

If a polygon is dilated by a scale factor of 3, the original polygon and its image are not congruent; rather, they are similar. Dilation changes the size of the polygon while maintaining the same shape, meaning corresponding angles remain equal and side lengths are proportional. In this case, the image will be three times larger than the original polygon. Therefore, while they share the same shape, they are not congruent.
