angle bisector
Divides corners equally
An angle bisector is a line or ray that divides an angle into two equal parts.
In geometry, every angle has exactly one bisector, which passes through the vertex and splits the original angle into two congruent angles: Draw the angle bisector to find the midpoint of the arc.
