1. we don't get to see the figure, so we don't know. If there is no figure, then it would be "sometimes true", since they have a common point J.
2. Two planes, if they meet, would meet along a line. Sometime they don't meet at all (parallel). So it is never true.
Determine if it is always sometimes never or always true
- ray LJ and ray TJ are opposite rays
-the intersection of two planes is a point
