What are the properties of parallelograms answer key geometry?

There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other.

Conditions for Parallelograms Both pairs of opposite sides are congruent. Both pairs of opposite angles are congruent. The diagonals bisect each other. One angle is supplementary to both its consecutive angles.

If a quadrilaterals is a parallelogram, then its opposite angles are congruent. If a quadrilateral is a parallelogram, then its consecutive angles are supplementary ($$ x + y =180). If a quadrilateral is a parallelogram, then its diagonals bisect each other.

SoMoreSo one rule that you need to remember for parallelograms is that opposite angles are congruent. So this means that angle b is equal to angle d. So b is x squared plus 20 and d is 7 x plus 50..
