Notice that the points N and K could be on the same line.
Postulate 2.3
Practice makes perfect
In the given figure, AK is in plane P and M is on NE. We will state the postulate that can be used to show the given statement is true.
Statement
N and K are collinear.
Looking at the figure, we can see that the points N and K could be on the same line. Therefore, Postulate 2.3 can be used to show that the given statement is true.
A line contains
at least two points.
