2-4 Angle Proofs

Part 2

Multiple Select

Select all true statements about complementary angles. 

• 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.  

Multiple Select

Select all true statements about supplementary angles. 

• 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.
