Final answer:

The answer explains why there must be at least two lines on any given plane by referencing mathematical theorems and providing examples.


Explanation:

Theorem 1:

Two straight lines of a plane have either one point or no point in common. For example, two intersecting lines on a piece of paper.

Theorem 2:

Through a straight line and a point not on it, one and only one plane can be created. Imagine a line on a piece of paper with a point above it forming a unique plane.

Theorem 5:

Every straight line in a plane divides the remaining points into two regions. This is evident when a line separates a drawing into two distinct areas.
