No, Danny is not correct
Here, we want to check the validity of the claims made by Danny
Firstly he determines that DE and BA are congruent
Secondly, he determines that the angle marked A and E are congruent
To use the SAS conguence definition, there needs to be a third determination. The third determination here is that the sides KE and AC must also be congruent
However, there is no evidence to support the fact that he determined that the sides KE and AC are congruent. Hence he cannot use the SAS congruence thoerem based on the two evidences ONLY
Hence, we can say that Danny is not correct
