2-4 Angle Proofs Pt. 2

If $m\angle A\ +\ m\angle B\ =90\degree$ , then the angles are complementary 

If  $\angle A\ and\ \angle B$  are complementary then  $m\angle A\ +\ m\angle B\ =90\degree$  

If  $\angle A\ and\ \angle B$  are complementary, then the angles are linear pairs. 

If $m\angle A\ +m\angle B=90\degree$ , then the angles are supplementary.  

If $m\angle A\ +\ m\angle B\ =180\degree$ , then the angles are complementary 

If  $\angle A\ and\ \angle B$  are supplementary, then  $m\angle A\ +\ m\angle B\ =180\degree$  

If  $\angle A\ and\ \angle B$  are supplementary, then the angles are linear pairs. 

If $m\angle A\ +m\angle B=180\degree$ , then the angles are supplementary.

 $\angle1\ and\ \angle2$  are supplementary

 $\angle1\ and\ \angle2$  are congruent

 $\angle1\ and\ \angle2\ are\ complementary$
