Line

In the given figure, 

How many line segments are formed with these three points?

What extends indefinitely on both sides?

What do we call the line segment extended indefinitely in both directions?

In the following diagram three lines $l,m,$ and $n$ are intersected by a transversal $t$, where $l\parallel m$, and $m\parallel n$. Prove that the lines $l$, and $n$ are parallel to each other.

Prove that “Lines which are parallel to the same line are parallel to each other”.

Two intersecting lines can intersect at only one point.

Arms of scissors represent parallel lines.
