Construction lines are used to help you position and locate other sketch entities. You can use construction lines for any shape such as a circle for location of a hole pattern, or a line, as I did in the screencast to locate the rectangle you asked for. Along with sketch constraints, you can position almost any sketch in the correct location. Construction lines are ignored by the application during modeling operations so they do not influence your design. The main thing to remember during sketching, make sure your sketches are fully constrained by sketch constraints and dimensions, normally in that order.

Creating parametric sketches is a skill but once you get it figured out it is very powerful and just as quick to create as dumb cad sketches.

If you ONLY want a line that bisects the rectangle vertically, without regard to any other constraints or relationships, sketch a Point. Constraint that Point the be Midpoint along one of the vertical sides of the Rectangle. Constrain that Point to be Coincident to the Line.
Now the Line will always bisect the Rectangle. The Rectangle and the Line are still free to move horizontally relative to each other, but their vertical relationship will be constrained.
Without any other relationships defined, it should look something like this:
