Answer:
13. QRT
14. T
15. There are infinite point of intersection of TR and plane P.
16. TQ
17. TR
Explanation:
13.
A plane name is defined by three non-collinear points which are lie on that plane.
From the given figure it is clear that point Q, R and T are three non collinear points which are lie on plane P.
Therefore, the name of plane P is QRT.
14.
From the given figure it is clear that line ST and line TR intersect each other at point T.
Therefore, the intersection of ST and TR is T.
15.
From the given figure it is clear that line TR lies on plane P. It means all the points of line lie on plane P.
Therefore, there are infinite point of intersection of TR and plane P.
16.
If STQ is a plane, then segment TQ lies on plane STQ and plane P.
Therefore the intersection of plane P and Plane STQ is TQ.
17.
If STR is a plane, then segment TR lies on plane STR and plane P.
Therefore the intersection of plane P and Plane STR is TR.
