1. A line or plane that divides an angle or dihedral angle into two equal parts.
Usage: technical; geometry

Examples

• The bisectrix of a right angle creates two 45-degree angles.
• In geometry class, we learned to construct a bisectrix using a compass and straightedge.
• The bisectrix divides the angle into two congruent parts.
• To find the bisectrix of an angle, you can fold the angle in half.
• The bisectrix is perpendicular to the sides of the angle in certain configurations.
