A-320 AutoPilot Localiser/Radial capture

[Maverick]

Dear fellow aviators,
I have 2 questions
1.ATC can vector an aircraft upto a maximum intercept angle of 90degrees while making an ILS/localiser approach or a VOR approach.
Is this true or false and reasons/comments please.
2.What is the maximum intercept angle ( if there is) for the autopilot to capture the localiser of an ILS or the radial/course of a V.O.R.
Can the autopilot for example capture the Localiser if is on a far away (lets say 20 nms.) downwind leg to the ILS approach of a runway.
thankyou,
Mav.
