Proving a uadrilateral is a Parallelogram
Determining Side Lengths in a Parallelogram
In quadrilateral ABCD, AD 1, BC.
What must the length of segment AD be for the
quadrilateral to be a parallelogram?
O 8 units
O 16 units
O 31 units
O 62 units
If a quadrilateral has a pair of sides that is both parallel and congruent, then the quadrilateral is a parallelogram.
Sides AD and BC are given as parallel.
If they are also congruent, then quadrilateral ABCD is a parallelogram.
3x + 7 = 5x - 9
-2x = -16
x = 8
AD = 3x + 7
AD = 3(8) + 7
AD = 31
i dont know it
let m = monomial
let t = trinomial
so, m times t = t.
monomial times a trinomial = another trinomial.
