Question

Are the following triangles similar? Justify your answer.​

Answer 1

if the triangles are indeed similar, then their corresponding sides will yield the same proportion or ratio, let's check, △MDC has 3 sides, a small one a medium and a large, same is true for △LON, so let's use hmmm say the small side of each and the medium side of each, to see if their ratio matches.  Check the picture below.
