According to the given information, segment AB is parallel to segment DC and segment BC is parallel to segment AD.. Using a straightedge, extend segment AB and place point P above point B. By the same reasoning, extend segment AD and place point T to the left of point A. Angles BCD and PBC are congruent by the Alternate Interior Angles Theorem. Angles PBC and BAD are congruent by the Corresponding Angles Theorem. By the __________ Property of Equality, angles BCD and BAD are congruent. Angles ABC and BAT are congruent by the Alternate Interior Theorem. Angles BAT and CDA are congruent by the Corresponding Angles Theorem. By the __________ Property of Equality, ∠ABC is congruent to ∠CDA. Consequently, opposite angles of parallelogram ABCD are congruent.

Okay, so basically you want us to fill in the blanks?

anonymous · Answer

Yes and i thought it was  Substitution and Reflexive but i am not sure i am horrible with word problems.

anonymous · Answer

Hahaha. Its okay. we are here to help

anonymous · Answer

Wait you said you thought it was substitution and reflexive. Did you get that wrong?

anonymous · Answer

No i was thinking it was the correct answer i just did not want to submit it and it be wrong i wanted a second opinion.

anonymous · Answer

So was I correct?
