math&ing001 · Answer

On the last CBD and CAE are similar I think. Otherwise all correct !

anonymous · Answer

@math&ing001 they are not similar $$\frac{ 6 }{ 10} \neq \frac{ 6 }{ 9}$$

anonymous · Answer

why would #18 also be AAA? I think SAS fits better, no? @purger

anonymous · Answer

if lines CD and AE are clearly parallel then you can use AAA too, but you are right, SAS is better.

anonymous · Answer

Ah okay, it's an either or type of thing. Thank you!
