If your teacher is asking "which of the following can be used to prove the triangles congruent?" then I agree with your statement that it's "none of the above". We simply don't have enough information to determine if the triangles are congruent or not. If we wanted to use SAS, then we'd have to know if EB = BD was true. If we wanted ASA, then we'd have to know that A = C. If we wanted AAS, then we'd have to know that E = D.
In short, you have the correct answer. Nice work.

hello ! here is an solution
Answer:
The error make by Josh is none .
Step-by-step explanation:
Given as :
The actual expression is written as ( - 20 a - 8 - 12 b )
The expression written by Josh as - 4 ( 5 a + 2 + 3 b )
Now, From the actual expression , if we take the common term
Then - 4 ( 5 a + 2 + 3 b )
The actual expression after taking common term 4 , is written as
- 4 ( 5 a + 2 + 3 b )
And The expression written by Josh is also - 4 ( 5 a + 2 + 3 b ) , which is the similar one.
So, no error makes by Josh
Hence The error make by Josh is none . Answer
