Let v1 and v2 be vectors in  that are linearly independent.

a) If all initial points of vectors are placed at the same point in , what geometric object do the linear combinations of v1 and v2 determine?

b) If v3 is a third vector in , what are necessary and sufficient conditions for v1, v2, v3 to be linearly independent in terms of this geometric object?
