divide polygon?

[bm23]

So, I have a plane of irregular shape plane which I extruded to make a concrete slab that acts as a floor. Now, I need to divide the surface (which is just 1 polygon) into a few, according to the shape of the rooms so that I can assign material to different parts of the floor. How can I do that?

I'm not at my home computer right now, so I'll have to just point you to a tutorial:

Thanks so much! I've managed to figure it out, using that link I use cut to add vertices and then manually position them myself
