Question

Which statement represents the biconditional statement of the conditional statements?

If the measures of two angles have a sum of 90º, then the angles are complements.

If two angles are complements, then their measures have a sum of 90º.




The measures of two angles do not have a sum of 90º if and only if the angles are complements.

The measures of two angles have a sum of 90º if and only if the angles are complements.

The measures of two angles do not have a sum of 90º if and only if the angles are not complements.

The measures of two angles have a sum of 90º if and only if the angles are not complements.

Answer 1

The measures of two angles have a sum of 90º if and only if the angles are complements.

if the angles are complementary they have to equal 90 otherwise they are not complementary

Answer 2

The measures of two angles have a sum of 90º if and only if the angles are complements.

if the angles are complementary they have to equal 90 otherwise they are not complementary
