According to the given Information, AB II DC and BC II AD . Using a straightedge, extend segment AB and place point P above poin
t B. By the same reasoning, extend segment AD and place point T to the left of point A. Angles
_are congruent by the Alternate Interior Angles Theorem.
Angles
__ are congruent by the Corresponding Angles Theorem. By the Transitive 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
Transitive Property of Equality, ABC is congruent to 2 CDA. Consequently, opposite angles of parallelogram ABCD are congruent.
What angles accurately complete the proof? (5 points)
