Question

As per an axiom in Euclidean geometry, if (two,three) points lie in a plane, the (plane,line,) containing those points also lies in the same plan.

Answer 1

2, line

Explanation:

Answer 2

Answer is TWO, LINE

If two points lie on the same plane, then the line containing them lies on the same plane. Think of two distinct points on a normal Cartesian coordinate grid. If both points are on the grid, then a line can be drawn between them on the same grid. In this case, the grid itself is the 2-dimensional plane.
