Answer:
1. Two
2. Line
Step-by-step explanation:
Two out of the five axioms of the Euclidean Geometry are:
1. A straight line can be drawn between any two points.
2. Any straight line can be extended infinitely.
So, from the above axioms, we get that 'If two points lie in a plane, a straight line can be drawn between those points and that line can be extended indefinitely in that plane'.
Hence, 'If TWO points lie in a plane, the LINE containing those points also lie in the same plane'.
