Exercise 66 Page 293

Points are coplanar if they lie on the same plane.

No, see solution.

Practice makes perfect

Let's recall that points are coplanar if they lie on the same plane. Consider the given diagram.

As we can see, points A, C, and J lie on plane ABC, so they are coplanar. However, the last point D is on BCD, not on ABC. Therefore, these four points are not coplanar.
