What are the missing reasons in the proof?
given: ▱abcd with diagonal line segment bd
prove: triangle abd is congruent to triangle cdb
diagram will be in the comments.
statements:
line segment ab is parallel to line segment cd
reason:
angle abd is congruent to angle cdb
reason:
triangle abd is congruent to triangle cdb
reason:

3. definition of a parallelogram

4. alternate interior angles theorem

5. reflexive property of congruence

6. asa

step-by-step explanation:

3. : )

4. same as 2

5. its kinda like a mirror

6. angle side angle postulate

i just took the quiz it should be right

Line segment ab is parallel to line segment cd
reason: since abcd is a  parallelogram and its characteristic is having two pairs of parallel sides. 
angle abd is congruent to angle cdb
reason: two parallel lines divided by a transversal have congruent alternate interior angles.
triangle abd is congruent to triangle cdb
reason: angle-side-angle

you for posting your question. i hope that this answer you. let me know if you need more .
