Test each statement below to see if it is reversible. if so, write it as a true biconditional. if not, write not reversible

1. complementary angles are two angles with measures that have a sum of 90.

2. a rectangle is a four-sided figure with at least one right angle.

Statement: Complementary angles are two angles with measures that have a sum of 90.
Reverse: Two angles with measures that have a sum of 90 are complementary angles.

Here the reverse is true, therefore, the statement is true biconditional.

Statement: A rectangle is a four-sided figure with at least one right angle.
Reverse: A four sided figure with at least one right angle is a rectangle.

Here, the reverse is not true, therefore, the statement is not reversible.
