Answer:
they are not alike
Explanation:
the triangles are similar, when their sides have a proportion, that is, when dividing side 1 by side 1 the result must be the same as dividing side 2 by side 2 and dividing side 3 by side 3.
Thus:
12/24 = 2
18/16 = 1,125
When the result is not the same we can affirm that they are not similar
