Answer:
The solution is given below;
Step-by-step explanation:
The explanation is as follows:
Given that
The coordinates are
A(-2, 8), B(2, 7), C(5, 1), and D(1, 2)
Based on this if the particular figure would be considered as a parallelogram
So,
A + C = B + D
(-2, 8) +(5, 1) = (2, 7) +(1, 2)
(-2+5, 8+1) = (2+1, 7+2)
(3, 9) = (3, 9)
As both are equivalent
Therefore ABCD is a parallelogram
