Question

7. Can a quadrilateral WXYZ be a parallelogram if:
a) Z+X = 180?
b) WX=ZY = 10 cm, WZ = 5 cm and XY = 5.5 cm?
c) W= 70° and Y = 65°?​

Answer 1

Answer:

no it cannot

Step-by-step explanation:

In a parallelogram,

• Z and Y are opposite angles so they must me equal
• if one pair of opposite side is equal ,then the other pair must also be equal
• W and Y are opposite angles so they must be equal

Answer 2

Step-by-step explanation:

x,y are co-interor angels

so,x+y=180

when x+y=180,then it becomes parallelogram
