Parallelogram. A parallelogram is a two-dimensional geometrical shape whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees.

The area of a parallelogram is the space enclosed between the four sides of a parallelogram. It can be calculated if we know the length of the base and the height of the parallelogram and it is measured in square units like cm2, m2, and inch2. Observe the following parallelogram which shows the base and the height. Consider the parallelogram PQRS w...

The Parallelogram. A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms! Example: A parallelogram with: all sides equal and. angles "A" and "B" as right angles.
In Euclidean geometry, a parallelogram is a simple (non- self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the ...
Select the quadrilateral that is a parallelogram. Recall the definition and properties of parallelograms. Parallelograms are quadrilaterals that have two pairs of opposite parallel sides. 2 Identify the parallelogram. Quadrilateral A is the parallelogram because, by the definition of a parallelogram, there are two pairs of opposite parallel sides.

Like all other quadrilaterals, the sum of all the angles of a parallelogram is 360°. The adjacent or the adjoining angles of a parallelogram add up to 180°. Therefore, ∠A + ∠B = 180°, ∠B + ∠C = 180°, ∠C + ∠D = 180°, and ∠D + ∠A = 180°. The diagonals of a parallelogram bisect each other. Here, OB = OD, and OA = OC.
