Question 1210461
.
In the diagram, AD bisects BAC.


By adding one more condition, we can prove that triangles ABD and ACD are congruent.  
Which one of the following could be that condition?  Select all that apply.

 
(a) BC = AD

(b) AB = PQ

(c) angle ABC = angle BPQ

(d) angle BCD + angle PAQ = 90

Neither the diagram nor the link to it are provided, so a reader does not have 
adequate information about the problem. Thus the input is meaningless.


As the problem is worded and presented in the post, the objects P, Q, and PQ are undefined, 
and, therefore, can not be used without explanations of their meaning.


So and therefore, as presented in the post, the problem is FATALLY DEFECTIVE
and the post itself can not be considered as a Math problem.


In general, recent parcels to this forum (of yesterday) produce very bad impression 
about the ability of their creator to compose adequate Math problems.



The fact that the Artificial Intelligence was employed to solve meaningless problem,
produce very bad impression about intentions of its authors.



Another attempt to deceive the reader.
