Euclidean Distance

Euclidean Distance measures the straight line between two points in Euclidean space, and it's calculated using the Pythagorean Theorem. For example, the distance between two points (x1,y1)(x1, y1) and (x2,y2)(x2, y2) is:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
