Parallel planes are planes that do not intersect.

A. Planes that do not intersect are parallel planes.

B. Planes that intersect are not parallel planes

C. This statement is not reversible.

D. Planes are parallel if and only if they do not intersect.

Answer 1

@Vocaloid would the 4th one be more accurate?

Answer 2

parallel planes are planes that do not intersect ===> true
planes that do not intersect are parallel --> true
so the statement is reversible, construct the biconditional

Answer 3

@Vocaloid so it's the first one then?

Answer 4

please review how to construct a biconditional statement

Answer 5

the 4th one seems correct to me?

Answer 6

good
