For a finite wing, the local relative wind differs by the free-stream

1.	For a finite wing, the local relative wind differs by the free-stream velocity by some angle. This angle is called as ____(a) Angle of attack(b) Twist angle(c) Relative angle of attack(d) Induced angle of attackThis question was posed to me in quiz.My question is from Downwash and Induced Drag in chapter Flow over Airfoils over Finite Wing of Aerodynamics
Answer» CORRECT option is (d) Induced angle of attack The BEST explanation: For a wing, induced velocity in the downward direction is PRESENT apart from the free-stream velocity. The resultant of both (RELATIVE local wind) is inclined to the free-stream velocity by an angle, which is called the induced angle of attack.
