Question

Answer my geometry plsss

Answer 1

1) ABCD is a parallelogram (given)

2) $\overline{BC} \parallel \overline{AD}, \overline{AB} \parallel \overline{CD}$ (opposite sides of a parallelogram are parallel)

3) $\angle BCA \cong \angle CAD, \angle BAC \cong \angle ACD$ (alternate interior angles theorem)

4) $\angle A \cong \angle C, \angle B \cong \angle D$ (congruent angles added to congruent angles form congruent angles)
