Figure ABCD is a parallelogram.
Which sequence could be used to prove that AD = BC?
First prove ABC is congruent to ACDA, and then state
AD and BC are corresponding sides of the triangles.
First prove A ABC is similar to ACDA, and then state AD
and BC are opposite sides of the parallelograms.
First prove OABCD is congruent to OCDAB, and then
state AD and BC are corresponding sides of two
parallelograms.
