An ordered pair x y represents co-ordinate of the point where x-coordinate or abscissa is the distance of the point from the centre and y-coordinate or ordinate is the distance of the point from the centre. C c is the longest side of a right triangle also known as the hypotenuse and. Enter the co-ordinate points and find the distance between two points.
The length of this line can be found by using the distance formula.
From the figure we have PR x2-x1 and QR y2-y1. Take the coordinates of two points you want to find the distance between. Given the two points x1 y1 and x2 y2 the distance d between these points is given by the formula. Derived from the Pythagorean Theorem the distance formula is used to find the distance between two points in the plane.
