They are not similar because one is bigger than the other one. Also, some of the sides are longer than the ones on the other side making them a slightly different shape.
Answer:
The two shapes are not similar. Meaning they are not the same shape and the corresponding sides are not proportional. At first when comparing corresponding sides it seems that ABCDEGF is 2 times bigger than HIJKLMN.
CD is 4 units & JK is 2 units (this is 2 times bigger)
DE is 2 units & KL is 1 unit (this is 2 times bigger)
EF is 2 units & LM is 1 unit (this is 2 times bigger)
FG is 1 unit & MN is 1 unit (THIS IS NOT 2 TIMES BIGGER)
