6-3 Notes: Proving that a Quadrilateral is a Parallelogram You can show that a quadrilateral is a parallelogram if you can show that one of the following is true. Def: Both pairs opp. Sides Parallelogram Both pairs of opp. Sides Parallelogram → Diagonals bisect each other Parallelogram → Both pairs opp. Angles Parallelogram → One pair of opp. Sides are both and Parallelogram → Determine if each quadrilateral is a parallelogram. Justify your answer. 1. 2. 3. Determine whether quadrilateral ABCD with the given vertices is a parallelogram. Explain. 4. A(2,5), B(5,9), C(6,3), D(3,-1) 5. A(-1,6), B(2,-3), C(5,0), D(2,9) Geometry Name____________________________________ Worksheet – 6.3 Parallelograms Date______________________Period_________
