This formula has been derived from the. Uses Herons formula and trigonometric functions to calculate area and other properties of a given triangle. The distance between x1 y1 and x2 y2 is given by.
Large dsqrt left x_ 2-x_ 1right 2left y_ 2-y_ 1right 2 Example For The Distance Formula.
Formula for distance is used to measure how far the objects are on a given line. For three points to be collinear the sum of the distance between two pairs of points is equal to the third pair of the points. Draw two lines parallel to both x-axis and y-axis as shown in the figure through P and Q. For two points 32 and 15 10 the distance is calculated as.
