Answer 2

Explanation:

The vertical bar, | , is a glyph with various uses in mathematics, computing, and typography. It has many names, often related to particular meanings: Sheffer stroke (in logic), verti-bar, vbar, stick, vertical line, vertical slash, bar, pike, or pipe, and several variants on these names.

You can type a straight vertical line, or "|," on most modern keyboards dating back to some of the 1980s IBM PCs. It's generally found above the backslash, so you can type a "|" by holding down the shift key and hitting the "" key.

In mathematics, the triple bar is sometimes used as a symbol of identity or an equivalence relation (although not the only one; other common choices include ~ and ≈). Particularly, in geometry, it may be used either to show that two figures are congruent or that they are identical.
