Multiple answers

Step-by-step explanation:

A parallelogram is a flat shape that has four sides. The two sets of opposite sides are parallel and of equal length to each other.

To prove that our figure is a parallelogram we first get the slope of our sides.

The formule we use to get the slope is:

m =

if we use our formule to calculate the slope of W-Z:

 =    =  8

if we use our formule to calculate the slope of X-Y:

 =    =  8

2. Then we have the W-X side that it's supossed to be parallel to Z-Y side

if we use our formule to calculate the slope of W-X:

 =    

if we use our formule to calculate the slope of Z-Y:

 =    

Then we have to prove that the parallalel sides are equal length to each other.

The formule we use to get the distance between two points is:

We calculate the lenght of the W-Z side that it's supossed to be equal to X-Y side:

W-Z = =  

X-Y = =

So the W-Z side have the same lenght to X-Y side.

We calculate the lenght of the W-X side that it's supossed to be equal to Z-Y side:

W-X = =  

Z-Y = =

So the W-X side have the same lenght to Z-Y side.
