Which sequence could be used to prove that AD = BC? First prove A ABC is congruent to ACDA, and then
state AD and BC are corresponding sides of the
triangles
First prove AABC is similar to ACDA, and then state
AD and BC are opposite sides of the parallelograms
First prove ABCD is congruent to DCDAB, and then
state AD and BC are corresponding sides of two
parallelograms
First prove ABCD is similar to CCDAB, and then
state AD and BC are opposite sides of the
parallelograms
