I guess you mean "A line drawn between 2 vertices which are not next to each other?":The line is a diagonal.
Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.

To find the length of a line drawn between 2 vertices which are not next to each other, first draw a right triangle such that the line is the hypotenuse and the other two lines are drawn parallel to the x-axis and y-axis. Since the length of the other two lines are known, you can then calculate the hypotenuse to find the length of the line between the two vertices.
