1. Plural of bisectrix; lines or planes that divide an angle or dihedral angle into two equal parts.
Usage: Primarily used in geometry and mathematics; Less common than the singular form 'bisectrix' or the anglicized term 'bisectors'

Examples

• The bisectrices of the angles in a triangle meet at a single point called the incenter.
• In geometry class, we learned to construct bisectrices using a compass and straightedge.
• The two bisectrices of the vertical angles are perpendicular to each other.
• Finding the bisectrices of a polygon's angles is essential for locating its incircle.
• The bisectrices divide each angle into two congruent parts.
