Respuesta :
Two planes that do not intersect are A. Always parallel. The definition of parallel planes is basically two planes that never intersect. The answer cannot be sometimes because planes cannot "sometimes" intersect and still be parallel. The answer cannot be never because two planes that "never" intersect ARE (always) parallel. Therefore the best and most correct answer is A.
The two planes that do not intersect are always parallel. From the definition of intersecting planes, "the planes intersect along a line if they do not intersect, they are parallel".
What is intersecting plane?
Intersecting planes are planes that intersect along a line. The planes P and Q intersect along the line m. If the planes P and Q do not intersect along a line. They are parallel. The figure is shown below.
What are parallel planes?
Parallel planes are planes in space that never intersect. Planes P and Q do not intersect, so they are parallel. The figure is shown below.
Completing the given statement:
The statement is "Two planes that do not intersect are always parallel.
From the above definitions, the planes that do not intersect along a line are always parallel.
Parallel planes have no common lines or points.
So, option A is correct.
