Verify that the vertices A(-6.1),B(2,-5),C(6,1) and D(2,4) are the vertices of a trapezoid. Does anyone know the steps to solve this? Thanks so much.

Answer 1

slope ab = -6/8 = -3/4
slope bc = 6/4 = 3/2
slope cd = 3/-4 = -3/4
slope da = -3/8
note AB is parallel to CD

Answer 2

thanks so much?
could you please tell me the formulas you used to get those answers?
