Atriangle is 3 inches wide and 1 inch tall. if its enlarged to a height of 4 inched, how wide will it be?

12 in

If the dilation is uniform, both height and width will be multiplied by 4.

New height = (1 in) × 4 = 4 in

New width = (3 in) × 4 = 12 in

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
