Based on the information in the diagram, determine whether the figure is a parallelogram. if so, select the answer with the correct justification.
a. no
b. yes, both pairs of opposite angles are congruent
c. yes, both pairs of opposite sides are parallel
d. yes, both pairs of opposite are sides are congruent.

d. yes, both pairs of opposite sides are congruent.

step-by-step explanation:

the opposite sides are congruent.   since both pairs of opposite sides are congruent, this means that they must be parallel; if they were not parallel, at least one pair of sides would not be parallel.  

since both pairs of opposite sides are parallel, this is a parallelogram.

1.true 2.false? ? i think. .

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
