Answer:

no, the triangles are not similar

Explanation:

The given ratios tell you corresponding side ratios are ...

ED : DC : EC = 8 : 10 : 12 = 4 : 5 : 6

AB : BC : AC = 12 : 15 : 21 = 4 : 5 : 7

Corresponding sides do not have the same ratios. The given information can be used to prove the triangles are NOT similar.
