In rectangle ABCD, the slope of ABState theslope of(a) BC(b) CD(c) DA |
|
Answer» We know that each angle of a rectangle is 90°, so angles A = B = C = D = 90° We know that when two lines are perpendicular to each other then the product of their slopes is -1 Slope of AD = 5/6 Since AD is perpendicular to DC, Slope of DC = -1/slope of AD = -1/(5/6) = -6/5 Like my answer if you find it useful! |
