Distance between two points (x 1,y 1) and (x 2,y 2) is given by: PQ = √[(x 2 – x 1) 2 + (y 2 – y 1) 2] It is known as distance formula. indeces_of_closest_point_in_list_2, distances = pairwise_distances_argmin_min(point_list_1, point_list_2) # Get index of a point pair that makes the smallest distance. From the points A and B drop perpendiculars to the coordinate axes. Square the difference for each axis, then sum them up and take the square root: Distance = √[ (x A − x B) 2 + (y A − y B) 2 + (z A − z B) 2] Example: the distance between the two points (8,2,6) and (3,5,7) is: Using the Pythagorean theorem, calculate the length of the hypotenuse AB: AB = √ AC 2 + BC 2. Let us solve some problems based on the distance formula. Finding the distance between two points on a coordinate plane. Use the Pythagorean Theorem to write the relationship between a, b and c.
