The name comes directly from Latin sagitta , meaning an arrow.

In geometry , the sagitta (sometimes abbreviated as sag [1] ) of a circular arc is the distance from the center of the arc to the center of its base. [2] It is used extensively in architecture when calculating the arc necessary to span a certain height and distance and also in optics where it is used to find the depth of a spherical mirror or lens.
