Question

1. a. explain why plane jkl is not an appropriate name for the plane below. b. give three names for the plane that would be appropriate.

Explanation:

a. A plane is named by three non - collinear points. Points J, K, and L are collinear, so naming the plane JKL is inappropriate as it does not uniquely identify the plane.
b. Three appropriate names could be based on three non - collinear points in the plane. For example, if we consider points J, K, and M (assuming M is not on the line JKL), we can name the plane JKM. Other names could be JML, KML as long as the three points are non - collinear in the plane.

Answer:

a. Points J, K, L are collinear, not enough to name a plane.
b. JKM, JML, KML
