Question

why is vsr not an acceptable name for this plane? r is not a point v is not on the plane they are all on the same line you only need 2 points to name a plane

Explanation:

In geometry, a plane can be named by three non - collinear points on the plane. If points V, S, and R are all on the same line, they cannot be used to name the plane as they do not define a unique plane.

Answer:

They are all on the same line
