Question

Prove that the points (-2,-1), (1,0),(4,3) and (1,2) are the vertices of a parallelogram.

Answer 1

Answer:

Step-by-step explanation:

Y2-y1/x2-x1=y3-y2/x3-x2

0+1/1+2=2-3/1-4

1/3=-1/-3

1/3=1/3

Yes the points form parallelogram

Hence proved

Answer 2

Step-by-step explanation:

Y2-y1/x2-x1=y3-y2/x3-x2

0+1/1+2=2-3/1-4

1/3=-1/-3

1/3=1/3
