Opposite sides are parallel by definition. Quadrilateral abcd is a parallelogram because ab dc and ad bc.

The area of a parallelogram is twice the area of a triangle created by one of its diagonals.

Characteristics of a parallelogram. The diagonals bisect each other. The diagonals of a parallelogram bisect each other. It has two pairs of parallel sides sides which never meet and four edges.

Consecutive angles are supplementary. Both pairs of opposite angles are congruent. Both pairs of opposite sides are congruent.

Other properties opposite sides of a parallelogram are parallel by definition and so will never intersect. Opposite sides are congruent. There are six important properties of parallelograms to know.

A parallelogram is a polygon with four sides a quadrilateral. The word parallelogram comes from the greek word parallelogrammon bounded by parallel lines. It is a quadrilateral that has opposite sides that are parallel to one another.

If one angle is right then all angles are right. Additionally there are two other characteristics that apply to rhombuses. Opposite sides are parallel adjacent angles are supplementary and the diagonals bisect each other.

Opposite angles are congruent. The opposite sides of a parallelogram have the same length they are equally long. Adjacent angles 180 rectangle.

A parallelogram is just one type of polygon. Diagonals bisect each other. Every rhombus is a parallelogram so it has all the characteristics of one.

Opposite sides are congruent ab dc. The area of a parallelogram is also equal to the magnitude of the vector cross product. To determine if the quadrilateral you re working with is a parallelogram you need to know the following 6 properties of parallelograms.

Parallelogram both pairs of opposite sides are parallel. Consecutive angles are supplementary a d 180. The parallelogram has the following properties.

Opposite sides are parallel. There are many characteristics of a rhombus. Opposite angels are congruent d b.

A parallelogram is a type of quadrilateral whose pairs of opposite sides are parallel.
