A line of symmetry
It is a line of symmetry
A figure that can be folded about a line so that its two parts match exactly is said to have line symmetry or reflectional symmetry. The line about which it can be folded is called the line of symmetry. Examples of such figures include a butterfly or a heart shape, where one half mirrors the other.
It is the solidus line that separates the numerator from the denominator in a fraction
A queue. In some parts of the world (USA) they use the word line.

Assuming that this refers to a line which has been cut into 2 parts, the parts would be called segments.

That is called an assembly line.
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.
If I understand your question, the shape would be "geometrical"
Self injury is never ever a good idea if you or someone you know is cutting yourself/themself you should call a self help line, or tell someone so they can help you.
