Which of the following determines a plane?A. a straight lineB. line and a point on the lineC. three collinear pointsD. 3 non-collinear points

Sagot :

Let us look at the definition of a plane in mathematics

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far.

A plane is not a line, it is a surface. And for us to have a surface, we must have at least 3 points that are non-collinear.

If the 3 points are colinear, we would still have a straight line and not a plane.

This makes the correct option to be "3 non-collinear points"

The answer is option D
