Question 1129802

Slope of AB:  (2-(-3)) / (6-(-2)) = 5/8
Slope of CD:  (2-7) / (0 - 8) = -5/-8 = 5/8<br>
So AB is parallel to CD<br>


Slope of AD:  (2-(-3)) / (0-(-2)) = 5/2
Slope of BC:  (7-2) / (8-6) = 5/2
So AD is parellel to BC<br>

Since AB || CD and AD || BC, ABCD forms a parallelogram. &#8718;
