Two or more shapes are known to be similar if the ratio of the similar sides of the figures is equal. The ratio of EH/AD is not equal to FE/BA, hence the rectangles ABCD and EFGH are not similar.
What are similar shapes?
Two or more shapes are known to be similar if the ratio of the similar sides of the figures is equal.
For the given rectangles ABCD and EFGH, for them to be similar, then;
EH/AD = FE/BA
Find the ratio of EH/AD
EH/AD = 6cm/2cm
EH/AD = 3
For the ratio of FE/BA
FE/BA = 8cm/4cm
FE/BA = 2
Since the ratio of EH/AD is not equal to FE/BA, hence the rectangles ABCD and EFGH are not similar.
