Q1: True or False: In a parallelogram, opposite sides are parallel and equal in length. The length of BC is equal to the length of AD. Consecutive angles are supplementary (A + D = 180°). The figure is a square. The diagonals of a parallelogram bisect each other. Diagonals bisect angles 7. What further condition would it have to satisfy to be 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. What figure is it? 12. 12. (c) The diagonals are perpendicular to each other. Diagonals are congruent. 2. ALL parallelogram properties apply 2. Some key properties … A pair of adjacent sides of a quadrilateral is equal c. Each pair of opposite sides of a quadrilateral is equal d. Each pair … Diagonals are perpendicular 6. Diagonals bisect each other 5. Property #1 Opposite sides of a parallelogram are congruent. (b) The diagonals bisect each other at right angles. 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. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. Opposite angels are congruent (D = B). The longer diagonal of a kite bisects the shorter one. Which of the following is a property of a parallelogram? The diagonals are perpendicular. The length of AB is equal to the length of DC. All Sides are congruent 4. Parallelograms can have angles that are not ninety degrees. Which of the following is NOT a property of a quadrilateral that is a parallelogram? The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither … (c) The diagonals are perpendicular to each other. a. Diagonals of a quadrilateral bisect each other b. (b) The diagonals bisect each other at right angles. To be a parallelogram, it . 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! "Contains four right angles" is the one among the following choices given in the question that is not a property of a parallelogram. If one angle is right, then all angles are right. (d) All angles are equal. The diagonals of a parallelogram bisect each other. (a) Opposite sides are parallel. All angles are right 3. A. Diagonals that bisect each other B. Diagonals that bisect opposit angles C. Two pairs of opposite congruent sides D.
