Question

(Parallelogram Proofs) Please Help!

Answer 1

m∠DAB = 90°
m∠ABC = 90°
m∠BCD = 90°
m∠CDA = 90° Definition of a Rectangle
segment AB is parallel to segment DC and segment BC is parallel to segment AD Converse of the Same-Side Interior Angles Theorem
Quadrilateral ABCD is a parallelogram Definition of a Parallelogram
Draw segment AC and segment BD by Construction with a straightedge
segment BA is congruent to segment CD Property of Parallelograms
(opposite sides are congruent)
∠BAD ≅ ∠CDA
segment AD is congruent to segment AD Reflexive Property of Equality
ΔBAD ≅ ΔCDA Side-Angle-Side (SAS) Theorem
segment AC is congruent to segment BD Corresponding Parts of Congruent Triangles are Congruent (CPCTC)


What reason completes the proof?
Alternate Interior Angles Theorem
Definition of Congruence
Property of Parallelograms
Same-Side Interior Angles Theorem
