Answer:
yes these are the vertices of a parallelogram
Step-by-step explanation:
we know that diagonals of a parallelogram bisect each other.
so, the coordinates of the mid point of AC = coordinates of the mid point of BD
A(-2,-1) B(1,0) C(4,3) D(1,2)
-2+4/2,-1+3/2= 1+1/2,0+2/2
2/2,2/2= 2/2,2/2
1,1=1,1
