Exercise 13 Page 279

Notice that the points N, K, and A are on the same plane.

Postulate 2.4

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 Points N, K, and A are coplanar. Looking at the figure, we can see that the points N, K, and A are on the same plane. Therefore, Postulate 2.4 can be used to show that the given statement is true. A plane contains at least three noncollinear points.
