Question

explain the distance formula in coordinate geometry​

Answer 1

Answer:

The coordinates of point P are (x1,y1) and of Q are (x2,y2). Then the formula to find the distance between two points PQ is given by: PQ = √[(x2 – x1)2 + (y2 – y1)2] Or. D = √[(x2 – x1)2 + (y2 – y1)2].

Answer 2

Distance between two points P(x1,y1) and Q(x2,y2) is given by:

d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula}

2. Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2.
