Q1: True or False: In a parallelogram, opposite sides are parallel and equal in length. 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. Solution:-(a) Opposite sides are parallel. The diagram of parallelogram is attached in image. (b) The diagonals bisect each other at right angles. Some key properties … If the perimeter of a parallelogram is 140 m, the distance between a pair of opposite sides is 7 meters and its area is 210 sq m, find the length of two adjacent sides of the parallelogram. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). A. The longer diagonal of a kite bisects the shorter one. Which of the following is a property of a parallelogram? The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither … Consecutive angles are supplementary (A + D = 180°). All angles are right 3. (d) All angles are equal. (a) Opposite sides are parallel. This is one of the most important properties of parallelogram that is helpful in solving many mathematical problems related to 2-D geometry. To be a parallelogram, it . In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. If one angle is right, then all angles are right. Diagonals are perpendicular 6. The length of AB is equal to the length of DC. Diagonals bisect angles 7. The correct option among all the options that are given … Diagonals bisect each other 5. (a) Opposite sides are parallel. The diagonals of a parallelogram bisect each other. What figure is it? (d) All angles are equal. (b) The diagonals bisect each other at right angles. The diagonals are perpendicular. "Contains four right angles" is the one among the following choices given in the question that is not a property of a parallelogram. The figure is a square. The diagonals of a parallelogram bisect each other. 2. Opposite angels are congruent (D = B). Parallelograms can have angles that are not ninety degrees. 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! The length of BC is equal to the length of AD. 12. A. Diagonals that bisect each other B. Diagonals that bisect opposit angles C. Two pairs of opposite congruent sides D. Two pairs of opposite congruent angles ALL parallelogram properties apply 2. Which of the following is NOT a property of a quadrilateral that is a parallelogram? All Sides are congruent 4. 1. (c) The diagonals are perpendicular to each other. 12.
