In geometry, the polar angle may be
- one of the two coordinates of a two-dimensional polar coordinate system;
- one of the three coordinates of a three-dimensional spherical coordinate system; in this case it is also called the zenith.
Famous quotes containing the words polar and/or angle:

“So much symmetry!
Like the pale angle of time
And eternity.
