Exercise 10 Page 7

To ensure that HJ is contained within the planes you choose, use H and J as two of the three points that define the planes.

Example Solution: Planes GHJ and HJL

Practice makes perfect

To ensure that the ray HJ is contained within the planes we choose, we will use H and J as two of the three points that define the planes.


For our first plane, we will choose the third point to be G, which gives us plane GHJ.


For our second plane, we will choose L as our third point, giving us the plane HJL. This plane contains the point K as well.
