A plane can be named using any three non-collinear points contained in the plane.
Example Solution: ALK
Practice makes perfect
A plane can be named using any three non-collinear points contained in the plane. Therefore, we are interested in all the points contained in the plane on the right (the blue plane).
There are seven points that lie in the plane. However, A, L, and B, and C, D, and E are collinear, so we cannot use these to name the plane. Instead, we can use K and any two of the other six points. One example of a correct name for this plane is ALK.
