Clearly you have never cut slabs, I assume you have an angle grinder? Trust me - dump this idea and buy proper kerbing/edging stones.
I dont see why you have got into triangles. Its simple a matter of depth of base (constant along the entire run by width of drive extension. Sharp sand on top of crushed hardcore (scalpings), lay slabs, and then brush a dry mortar mix and then water with a hose set on fine spray.
Edit, and why use a different size slab? its going to look silly
