A line segment or ray that divides an angle into two congruent parts is called an angle bisector. It originates from the vertex of the angle and extends outward, ensuring that the two resulting angles on either side of the bisector are equal in measure. Angle bisectors are significant in various geometric constructions and proofs, often used in the context of triangles and other polygons.
the line of symmetry
the middle of something divides it into two equal parts not the center because the center divides it into 4 equal parts
A point on a line segment that divides the segment into two equal parts is a midpoint.
A line segment that divides a circle in two is a chord.If the two parts of the circle are equal, the line segment is a diameter.See 'The Parts of the Circle' in Sources and related links, below.
