(geometry) Euclidean distance - the distance between two points defined as the square root of the sum of the squares of the differences between the corresponding coordinates of the points; for example, in two-dimensional Euclidean geometry, the Euclidean distance between two points a = (aₓ, a_y) and b = (bₓ, b_y) is defined as:

a long-distance cross-country skiing race (such as at the Olympics)

metric space

astronomy

a system of measurement

(linear algebra) identity matrix

an imaginary unit

a derived unit
