AB = x + 4 DC = 12 AD = x + 2 BC = ? Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent. Show t
postnew [5]

Answer:

  AB = DC = 12

  AD = BC = 10

Step-by-step explanation:

For ABCD to be a parallelogram, opposite side pairs must be congruent. That will be the case when ...

  AB = DC

  x+4 = 12 . . . . substitute expressions for length

  x = 8 . . . . . . . subtract 4

Then the lengths of AD and BC must be ...

  BC = AD = x+2 = 8+2 = 10

___

The figure will be a parallelogram when x=8 and sides have lengths ...

  AB = DC = 12

  AD = BC = 10

_____

<em>Comment on the problem</em>

Of course, if x ≠ 8, or BC ≠ AD, the figure will not be a parallelogram. You are asked to show the figure IS a parallelogram, but all you can really show is that the figure CAN BE a parallelogram. In order to do anything useful with the given expressions for side lengths, <em>you must assume the figure is a parallelogram</em>.
