In geometry, the sagitta (sometimes abbreviated as sag[1]) of a circular arc is the distance from the midpoint of the arc to the midpoint of its chord.[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. The name comes directly from Latin sagitta, meaning an "arrow".
