Perpendicular slope theorem

WebAug 17, 2024 · Solution 1 Translate two lines so that their intersection is the origin and then take two vectors along each line, say u = ( 1, k 1), v = ( 1, k 2). The two lines are perpendicular if and only if u ⊥ v, viz u ⋅ v = 1 + k 1 k 2 = 0 This explains why k 1 is the negative reciprocal of k 2. Solution 2 WebGiven the equation y=mx + b, we can draw a triangle ABC with the vertical leg length m and the horizontal leg length 1. Next draw triangle ADE with DA perpendicular to AC. ADE is congruent to ABC since angle DAE=angle …
