My answers:

11. rhombus, square
12. 540º

Right.

Your answers are correct.
In problem #9, right, scalene, and isosceles describe types of triangles, but some triangles can fit two of the definitions. 
Okay, I think that is why I was confused. But #9 is still right, no?

Thank you, Ms. Sue and "drwls"!
