To be considered similar, two polygons sometimes have corresponding sides that are equal.

"  Two figures are said to be similar if the ratio of each of the corresponding  sides of the two figures are equal "

Hence, if both the figures have sides of equal length then obviously the ratio of each of the corresponding sides is equal i.e. 1:1.

Also, the ratio may be same if the original figure is dilated by some scale factor.

This means that now in this case the corresponding sides are not equal.

its the fourth option

your answer is b ^w^ hope i
