Best ResponseYou've already chosen the best response.0A student wrote the following sentences to prove that the two pairs of parallel opposite sides of parallelogram ABCD are congruent: For triangles ABD and CDB, alternate interior angles ABD and CDB are congruent because AB and DC are parallel lines. Alternate interior angles ADB and CBD are congruent because AD and BC are parallel lines. DB is congruent to DB by _______________. The triangles ABD and CDB are congruent by ASA postulate. As corresponding parts of congruent triangles are congruent, AB is congruent to DC and AD is congruent to BC by CPCTC. Which phrase best completes the student's proof?

Best ResponseYou've already chosen the best response.0also reflexive property is x=x transitive property says if x=a and b=x, then a=b associative property is (a+b)+c=a+(b+c) substitution property is something like if a=b and b<c, then a<c (See how b was replaced with a; we substituted a for b since a=b)
