For the Quadrilaterals test you may use 1 pg handwritten notes (front and back) and your beige sheet. I suggest that you use either the “Quadrilaterals Resource Page” notes that we did in class or the Quadrilaterals “tree,” but you could also make your own page. You may also use a calculator.

17. [pic]given, use opposite sides of a parallelogram are congruent by def’n of a parallelogram and that SQ is congruent to itself by the reflexive prop of congruence. Then triangle PSQ is congruent to triangle RQS by SSS. Then angle PSQ is congruent to angle RQS by CPCTC. Angle PQS is congruent to angle RQS by definition of angle bisector. Angle RSQ is congruent to angle PSQ by transitive property of congruence and SQ bisects angle PQR by definition of angle bisector.
