In this lesson our instructor talks about point, line, and plane postulates. She talks about seven different postulates about points, line and plane. She discusses using the postulate in example problems. Four complete extra example videos round up this lesson.
A postulate (also called an axiom) is a statement that is assumed to be true. It is accepted as fact without formal proof.
Through any two points, there
is exactly one line
Through any three points not
on the same line, there is exactly one plane
A line contains at least two
A plane contains at least
three points not on the same line
If two points lie in a plane,
then the entire line containing those two points lies in that plane
If two lines intersect, then
they intersect in exactly one point
If two planes intersect, then
their intersection is a line
Point, Line, and Plane Postulates
