Answer 1

SAS Postulate

Answer 2

Answer 3

The opposite sides of a parallelogram are congruent. So you have SSS (the triangles share a common side, and the other 2 sides are part of the parallelogram)

The opposite angles of a parallelogram are congruent. Using the above (congruent sides) you could also do SAS.
