Geometry
binomial
It means that they are continuous in both directions
Arrow heads on lines usually signifies parallel lines
You have to press the middle button that has the arrow and the two lines.
An arrow (→) has one line of symmetry. A double-headed arrow (↔) has two lines of symmetry and rotational symmetry if you want to claim it.
To indicate that a pair of lines are parallel you mark them both with an arrow. If there is another pair of parallel lines on the same shape you mark those with a double arrow.

There are infinitely many lines in mathematics and geometry.
A vertex, in Mathematics, is the meeting point of two lines that form an angle. In other use it is the highest point, or the top, of anything.
2. actually, none, the lines are intersecting
