Parallelograms ______________________ bisect each other. Parallelograms have opposite sides that are _________________. There are 5 properties of a Parallelogram. Complete the properties by matching the correct word to each sentence. diagonals ? opposite ? consecutive ? not used: congruent ? parallel ? complementary ? True or False?
In a quadrilateral, if one pair of opposite angles are congruent then it is a parallelogram? True, it only takes one pair of opposite angles congruent. False, not enough information. True or False? If one pair of opposite sides are congruent and parallel then its a parallelogram. True, it only takes 1 pair of opposite sides that are parallel and congruent. False, not enough information P 55∘ False, there is not enough information True, one angle is supplementary to it's consecutive angles. Given the information above, the figure is a parallelogram. O 125∘ T 55∘ R S The figure above is a parallelogram. True, it only takes one pair of opposite angles congruent and one pair of opposite sides congruent. False, not enough information. K 130∘ 130∘ P I C The figure, CAKE, above is a parallelogram. E True, it only takes both pairs of opposite sides congruent to be a parallelogram. False, not enough information. A K Based on the given information, can you prove the figure is a parallelogram? yes, 2 opp. sides are parallel & congruent no, not enough information yes, diagonals are congruent yes, diagonals bisect each other Find the value of x that would make EFGH a parallelogram.
