Question

if a(x1, y1), b(x2, y2), c(x3, y3), and d(x4, y4) form two line segments, and , which of these conditions needs to be met to prove that ?

Answer 1

Find the slope of AB, let's say its m1 Find the slope of CD, let's say it's m2 For 2 lines to be perpendicular to each other they need to satisfy the condition: m1 x m2 = -1
