| March 2, 2021 | education
The plane, as is known, can be specified by three points that do not lie on one straight line.
By definition, two points are required to define a line.
Since we need to define a plane through a straight line, we take two points lying on a given straight line and one outside this straight line. It turns out that we can choose this “free point” in space anywhere, except for our straight line. Therefore, there are infinitely many planes.
Answer: An infinite number of planes can be drawn through a straight line.
