A) Perpendicular
B) Parallel
C) Angle between them is \[\frac{\pi }{4}\]
D) None of these
Correct Answer: A
Solution :
Mid point of the points \[(a\cos \alpha ,a\sin \alpha )\] and \[(a\cos \beta ,a\sin \beta )\] is, \[P\left( \frac{a(\cos \alpha +\cos \beta }{2},\frac{a(\sin \alpha +\sin \beta )}{2} \right)\].You need to login to perform this action.
