Question

rewrite the following statement as a biconditional: \supplementary angles add up to 180\. if two angles add up to 180° then they are supplementary. you cant it is conditional. two angles are supplementary if and only if the sum of the measure of the two angles is 180°. if two angles sum does not equal 180° then they are not supplementary.

Explanation:

A biconditional statement combines a conditional statement and its converse. The original statement is "Supplementary angles add up to 180". The biconditional should state that two - angles are supplementary if and only if their sum is 180 degrees.

Answer:

Two angles are supplementary if and only if the sum of the measure of the two angles is 180°.
