Prove quadrilateral ABCD Is a parallelogram A(-2, 8), B(2, 7), C(5, 1), and D(1, 2)

The solution is given below;

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

the following sets of characteristics describe what we know about the outer plants is c. rocky surface, closet to the sun and larger in size
