(a) Opposite sides are parallel. Opposite angels are congruent (D = B). "Contains four right angles" is the one among the following choices given in the question that is not a property of a parallelogram. In this worksheet, we will practice determining whether a quadrilateral is a parallelogram or not and using the properties of parallelograms to find unknown angles or lengths. In geometry, a parallelogram is a convex quadrilateral polygon that is characterized by having 2 sets of parallel sides.In other words, a parallelogram is a 4-sided figure in which opposite pairs of sides lie parallel to each other. 1. The diagonals of a parallelogram bisect each other. This is one of the most important properties of parallelogram that is helpful in solving many mathematical problems related to 2-D geometry. Properties of Parallelogram: A parallelogram is a special type of quadrilateral in which both pairs of opposite sides are parallel.Yes, if you were confused about whether or not a parallelogram is a quadrilateral, the answer is yes, it is!
