- 1Distance Formula |P1P2| = √[(x2 − x1)2 + (y2 − y1)2]Midpoint Formula
M (x, y) = [½(x1 + x2), ½(y1 + y2)] - 2Section Formula (Internal division) P(x, y) = [(m1x2 + m2x1)/(m1 + m2), (m1y2 + m2y1)/(m1 + m2)]Section Formula (External division)
P(x, y) = [(m1x2 – m2x1)/(m1 – m2), (m1y2 – m2y1)/(m1 – m2)]
