1.

 

I think it is 4, 5.

 

 

This is because of SAS theorem, the other choices don't match up to SAS, remember that the sum of the angles on a triangle add to 180. That means triangle 5 also has an angle of 45.

 

2. 

 

I think it is 3, 5

 

This is AAS theorem, and only 3 and 5 match the AAS exactly.

The second one is 3,5  due to AAS rule.
