Hello i have a question that i do not really understand if you could make a good explanation on how you got ur answer i would appreciate it and i can make u branliezt. So the question is 5x 10 1 x20. (On the 10 there is a 1 but it is a really small 1 that comes after the 10. I did not really understand this one so please help me)

D: Triangles ABD and CDB are congruent by the ASA postulate instead of the SAS postulate.

Step-by-step explanation:

I got it right on the test for one, but two, we must look at the two lines before:

1.) Similarly, alternate interior angle ADB is equal to angle CBD because AD and BC are parallel lines.

So we have two angles, and:

2.) DB is equal to DB by the reflexive property.

So, we see that we have two angles, and one line, what is that? That is ASA! Not SAS, now if the proof provided an angle and a line on 1, and then the reflexive property in 2, then SAS would be correct, but the proof called two angles and that side, so they need to say ASA.
