Quadrilateral abcd has vertices a(1, 0) b(5, 0) c (7, 2) d(3, 2). use slope to prove that abcd is a parallelogram.

In here, we will use the slope formula in order to prove that ABCD is a parallelogram. The slope of AB must be equal to CD and the slope of BC must be equal to DA. Using the formula m = (y1-y2) / (x1-x2), we obtain the slope for AB = 0/4, BC = 1, CD = 0/4, DA = 1. We can say that ABCD is a parallelogram as it satisfies AB = CD, and BC = DA

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
