Example Solution: Through points K, H, and L there is exactly one plane, which is plane M.
Practice makes perfect
The Three Point Postulate tells us that through any three non-collinear points there exists only one plane. Examining the diagram, we see five points on the plane: J, G, K, L, and H. Note that even though H does not have a dot it is still a point, as the intersection between two lines is by definition a point.
One possible example of the postulate is through points K, H, and L there is exactly one plane, which is plane M.
