Chapter 8.1, Problem 64E

To determine

To sketch: The given three possibilities.

Explanation of Solution

Given information: The following possibilities are given to sketch:

• Three planes that never intersected.
• Intersection in one line.
• Intersection in one point.

Sketch: The given situations are sketched below.

• Three planes never intersected each other if they are parallel to each other.

  

• Intersection in one line: Draw any three planes that intersect in a line.

  

• Intersection in one point: If first two planes intersect in a line and third plane contains only one point on that line, then this situation is possible.
