Test the following statement to see if it is reversible. if so, choose the true biconditional. parallel planes are planes that do not intersect. planes that do not intersect are parallel planes. planes are parallel if and only if they do not intersect. planes that intersect are not parallel planes this statement is not reversible.

The converse of the first example is not true (e.g. if |x| = 3, x != 3 necessarily. x might be -3)

"Parallel planes are *not* planes that *do* intersect." This statement is true, so planes are parallel if and only if they do not intersect.

The third statement is false, to begin with -- a rectangle requires at least three right angles (from which the fourth one is also a right angle)

The converse statement is: "A rectangle is *not* a four-sided figure with *no* right angles" The converse is true (e.g. a rectangle is not a diamond-like quadrilateral), but the initial statement is false.
