HELP I WILL GIVE BRAINLIEST

Prove that in parallelogram both pairs of opposite angles are congruent (Theorem). Please provide an answer in the "statement and reason" format.

Explanation:

Statements are numbered; reasons are in italics.

1. ABCD is a parallelogram with AB≅CD and BC≅AD. Given; definition of a parallelogram.

2. Diagonal AC ≅ diagonal CA. Reflexive property of congruence.

3. ΔABC ≅ ΔCDA. SSS congruence postulate.

4. ∠B ≅ ∠D. CPCTC. (Opposite angles B and D are congruent.)

5. Diagonal BD ≅ diagonal DB. Reflexive property of congruence.

6. ΔABD ≅ ΔCDB. SSS congruence postulate.

7. ∠A ≅ ∠C. CPCTC. (Opposite angles A and C are congruent.)

6e14 is the answer.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
