true or false:
if nonzero vectors u and v have the same magnitude they make equal angles with u + v

Question

true or false:
if nonzero vectors u and v have the same magnitude they  make equal angles with u + v

dumbcow · Answer

id say true

anonymous · Answer

I'm not sure what you mean by make equal angles with u + v

anonymous · Answer

@polpak : draw two general vectors (say u and v ) in the first quadrant , and draw the vector representing their sum , now since the magnitude of u and v were equal then we have two sides of the triangle equal ( which means it is isosceles , with equal base angles , and these base angles are the angle that (u) makes with ( u+v ) , and the angle that (v) makes with (u+v).

so , given that interpertation it would be true
