Okay, thanks! Do you know how to determine whether triangles are similar?

Answer 13

I can't explain very well so I hope this site will help you.

All angles are equal.
Corresponding sides have same ratio

Answer 14

Okay, it's just that I had one more question that I don't know how to respond to.

Answer 15

What is that?

Answer 16

Yes the triangles are similar. The corresponding sides are \(NP-NM\) and \(NO-NL\).
The ratio is \(\large \frac{NP}{NM}=\frac{NO}{NL}=\frac{2}{3}\)

Thanks! You've been a big help.
