Question

The least number of non-collinear points required to determine a plane is:

• A. one
• B. two
• C. three
• D. infinite

Answer 1

The correct option is C three

The points which do not lie on the same line are known as Non-collinear points.

If we plot two points, it determines the equation of a line.

Since, at-least two points determine a line.

If we add one more point, it will become a plane.

Thus, at-least three points are required to determine a plane.

Hence, option C is correct.
