Is triangle COW ~ triangle PIG identify the similarity postulate or theorem that applies
ch4aika [34]
We can see that OW/IG = 5/15 = 1/3 and CW/PG = 7/21 = 1/3. So we have two ratios that result in the same value (1/3). We would need to know if CO/IP is also 1/3 as well, so we can use the SSS similarity theorem. However we don't have that information. So we can't use SSS. 

Alternatively, if we knew that angle CWO = angle PGI, then we can use the SAS similarity theorem. But that bit of info isn't given to us, so we can't use SAS either.

AA can't be used because we don't know anything about any pairs of angles. 

-------------------------------------------------------------------------

In short, the answer is choice D. It cannot be determined. There isn't enough information.
