Answer:
- A. Points A, B, and D are on both planes.
- B. Point H is not on plane R.
- D. Points C, D, and A are noncollinear.
- E. The line containing points F and G is on plane R.
Step-by-step explanation:
A. Points A, B, and D are on both planes.
-- true. These points are on the line of intersection of the planes, so are in both planes.
B. Point H is not on plane R.
-- true. Point H is not shown as being on either of the identified planes.
C. Plane P contains point F.
-- false. Point F is shown as being in plane R, not P.
D. Points C, D, and A are noncollinear.
-- true. Point C is not on the line containing points A and D.
E. The line containing points F and G is on plane R.
-- true. F and G are both in plane R, so the line containing them will also be in that plane.
F. The line containing points F and H is on plane R.
-- false. Point H is not in plane R, so will not be on any line in plane R.
