The true statements are:
- Points A, B, and D are on both planes.
- Point H is not on plane R.
- Points C, D, and A are noncollinear.
- The line containing points F and G is on plane R.
If two planes are said to have intersect each other, the intersection will be regarded as a line.
Hence, looking at the image attached, you will see that Points C, D, and A are noncollinear and the line containing points F and G is on plane R.
Note that when a line and a plane are said to intersect each other , the intersection will be a single point, or say a line. So Points A, B, and D are on both planes.
Therefore, option 1, 2, 4 and 5 are correct.
