Given angle 1 Â and angle 2 are supplementary angles
When two angles are said to be supplementary then the sum of angles = 180 degree
<1 + < 2= 180
Two angles are supplementary angles whose measures sum to 180 degree is a theorem
a theorem can be used as a reason in the second column of a two-column proof
Definition of supplementary angles states that two angles are supplementary angles whose measures sum to 180 degree Â
Definition of supplementary angles is the reason should go in box 2, of the two column proof
