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.
Every line bisector divides a line into two halves: by definition!
A cord that crosses the center of a circle is a diameter, which divides the circle into two equal halves. It is a line segment, and it is the longest cord that can be drawn within a circle.However, if the segment begins at the center rather than crosses through it, and has the other endpoint on the circumference of the circle, it is not a cord, but is a radius of that circle.
The imaginary line that divides the body into equal right and left halves is known as the midsagittal or median plane. This plane runs vertically through the center of the body, creating symmetrical halves. Any plane parallel to this line is referred to as a sagittal plane.
That line is called a "Diameter".

It is called a great circle. The equator is an example.

The other name for the line of symmetry of a circle is the diameter. The diameter of a circle is a line segment that passes through the center of the circle and has endpoints on the circle itself. It divides the circle into two equal halves, making it a line of symmetry. This means that if you were to fold the circle along the diameter, both halves would perfectly overlap.
You are drawing a line which divides the angle into 2 equal parts (halves).
