•  diagnols bisects, are congruent and perpendicular

•  a parallelogram with four congruent sides
• 2 pair of congruent angles
• diagonals bisects each other and are congruent

• 2 pair of congruent sides
• opposite angles are congruent other is non-congruent
• diagnols bisects a pair of opposite angles

• 2 pairs of congruent sides but one pair is parallel
• consecutive angles are supplementary
• bisects an angle or each other

•    one pair of  non-parallel sides called legs, if legs are congruent its a isosceles trapezoid, and one pair of parallel sides
