Now, how can we determine the distance between P and Q. The distance of a point from the x-axis is known as its y-coordinate, or ordinate. As discussed, the distance formula is used to find the distance between any two points, when we already know the coordinates. Formula for Distance Between Two Points The formula for the distance, d d, between two points whose coordinates are (x1,y1) (x 1, y 1) and (x2,y2 (x 2, y 2) is: d = √(x2 −x1)2 +(y2 −y1)2 d = (x 2 − x 1) 2 + (y 2 − y 1) 2 This is called the Distance Formula. The formula for the distance between two points in the plane can be extended to two points in space. d = distance (m, inches ...) x, y, z = coordinates. Therefore co-ordinates of the point  which are equidistant from the points A,B,C and O is given by$$(\frac{a}{2},\;\frac{b}{2},\;\frac{c}{2})$$..
