The distance between two points is the same as the length of the hypotenuse of a right triangle with the two given points as endpoints, and the two sides of the right triangle parallel to the x-axis and y-axis, respectively. The length of the segment parallel to the x-axis is the difference between the x-coordinates of the two points. The length of the segment parallel to the y-axis is the difference between the y-coordinates of the two points. Use the Pythagorean Theorem a2+b2=c2 or c=√(a2+b2) to find the distance. The formula is: “distance”=√((x_2-x_1 )2+(y_2-y_1 )2).
