What is Distance Formula?
We use Pythagorean theorem to determine the required distance. Distance formula states that the distance between any two coordinates is equal to the square root of the differences between the x-coordinates and y-coordinates of the points. It is used to evaluate the distance between point to point, point to plane, and plane to plane.
The image added below shows, two points A(x, y) and B(x, y) and we will find the distance between them,
Distance Formula
The formula to calculate the distance between two points is,
D = √((x2 – x1)2 + (y2 – y1)2)
where,
- D is the distance between the points A and B
- (x1, y1) and (x2, y2) are the coordinates of A and B respectively
How to find Equidistant Points on Y-Axis?
Distance formula is used to calculate the distance between any two points in a two-dimensional or three-dimensional plane. To find equidistant points on the y-axis we use the distance formula.
