Answer 1

The figure below shows a parallelogram PQRS:

A parallelogram PQRS is shown with the diagonal SQ.

The flowchart shown below shows the sequence of steps to prove the theorem: Opposite angles of a parallelogram are equal:

Which is the missing statement?

Answer - Triangle PQS is congruent to triangle RSQ

Answer 2

Answer by Mimiwhatsup: Triangle PQS is congruent to triangle RSQ

Why is this right by Mimiwhatsup: As the PQ shows it is equal to SR
