Distance between two points in 2D space

Distance between two points is calculated by creating a right-angled triangle using the two points.The line between the two points is the hypotenuse (the longest side, opposite to the 90° angle). Lines drawn along the X and Y-axes complete the other sides of the triangle, whose lengths can be found by finding the change in X and change in Y between the two points.We will use the Distance formula derived from Pythagorean theorem.
