Bisectrix

From Wikipedia, the free encyclopedia

Bisectrix (fem. of Lat. bisector, from bi-, "two", secare, "to cut"), in geometry, is the same as bisector, i.e. a point which divides a line, or a line which divides an angle, into two equal parts. In crystallography it denotes the bisector of the angle between the optic axes.
