# Title: What is Distance Formula in Maths

• Distance between two points is the length of the interval joining the two points.
• If the two points lie on the same horizontal or same vertical line, the distance can be found by subtracting the coordinates that are not the same.
• In analytic geometry, distance formula used to find the distance measure between two lines, the sum of the lengths of all the sides of a polygon, perimeter of polygons on a coordinate plane, the area of polygons and many more.
• As an example, we can find the lengths of sides of a triangle using the distance formula and determine whether the triangle is scalene, isosceles or equilateral.

## How to Find the Distance between Two Points

• The distance between two points of the can be found using the distance formula.
• 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.
