Unit 6-3 Conditions for Parallelograms

**Standard 6d:**Prove that a given quadrilateral is a parallelogram.

- Proving parallelograms
- If the opposite sides of a quadrilateral are congruent, then it is a parallelogram.
- If the opposite angles of a quadrilateral are congruent, then it is a parallelogram.
- If the consecutive angles of a quadrilateral are supplementary, then it is a parallelogram.
- If one pair of opposite sides are parallel and congruent, then the quadrilateral is a parallelogram.
- If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.
