Here, we are required to determine the intersection of plane R and P, the point which is not on plane P, the point where CE and DB intersect.
- First line: Line DB
- Second line: Point H
- Third line: Point D.
For the first line:
- The intersection of two planes is usually a line.
- Therefore, although Point D and B are intersection points, the intersection of plane R and P is (line DB)
For the second line;
- Among points H, D, C, B, only point H is not on plane P.
For the third line:
- From observation, the line CE and line DB intersect at point D.
