Basically better flow by avoiding horizontal sections immediately following a vertical one.
The "normal" bends are 87°.
And where do they go?
At 87°, I suspect 3° for slope at a junction with a T-piece, but where does a bend come into play? - a sink always has a trap bend, so I don't understand the OP's question.
