HEL PLEASE The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent: BС AD. According to the given information, AB || DC and BC ||AD . Construct diagonal A C with a straightedge. Angles BAC and DCA are congruent by the Alternate Theorem. Angles BCA and DAC are congruent by the same theorem. Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem. By CPCTC, CD, as well as sides BC and DA, are congruent.

Which sentence accurately completes the proof? Angles BAC and DCA are congruent by the Same-Side Interior Angles Theorem.

A) Angles BAC And DCA are congruent by Same side Interior angles theorem
B)Diagonal BD is congruent to itself by the reflexive property of equality
C) Diagonal AC is congruent to itself by the reflexive property of equality
D)Angles ABC and CDA are congruent according to a property of parallelograms (opposite angles congruent)​
