Euclidean distance is the most commonly used measure of similarity in many classification and clustering algorithms. It measures the straight-line distance between two points in Euclidean space. The square of the Euclidean distance is also commonly used as a similarity measure. The other options, Chebychev's distance, Manhattan distance, and City-block distance, are all distance measures but not as commonly used as the Euclidean distance in similarity calculations.
