PROOF OF THE DISTANCE FORMULAS First Proof: Distance amid primaeval points co ordinates is a basic concept in geometry.Now, we sustain an algebraic expression for the same. Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Let P1Â (x1, y1) and P2 (x2, y2) be 2 points in a Cartesian plane and denotes the distance surrounded by P1 and P2 by d(P1, P2) orÂ byÂ P1P2. retreat the line component part Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â The segment is parallel to the x axisÂ Then y1 = y2. thread P1 L and P2 M, perpendicular to the x-axis. Then d(P1,P2) is equal to the distance amid L and M. But L is (x1, 0) and M is (x2, 0). Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â So the continuation LM = |x1-x2| Hence d (P1, P2) = |x1-x2|.

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â therefore, [d(P1,P2)]2= |x1-x2|2+ |y1-y2|2 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =(x1-x2)2+(y1-y2)2 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =(x2-x1)2+(y2-y1)2 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â d(P1,P2) = insect bite Proof The Distance Formula is a variant of the Pythagore an Theorem that you apply back in geometry.! Heres how we wash up from the one to the former(a): Â hypothecate youre given the two points (2, 1) and (1, 5), and they want you to reign bulge out how farthest apart they are. The points look like this:| Â Â | Â Â Â | Â You can get off in the lines that form a well(p)-angled trigon, using these points as two of the corners:| Â Â | Â Â Â | Â Its easy to find the lengths of the horizontal and vertical sides of the right triangle: just subtract the x-values and the y-values:| Â Â | Â Â Â Â | Then use the Pythagorean Theorem to find the length of the third side (which is the hypotenuse of the right triangle): c2 = a2 + b2 ...so: Â Â secure Â© Elizabeth Stapel 1999-2009 either Rights Reserved This format always holds true.
