1.) name three two pairs of adjacent angle 2.) name two pairs of complementary 3.)name three pairs pairs of vertical angles 4.)two linear pairs5.)name a pair of supplementary angles
Answer (1)
Answer:1. Three pairs of adjacent angles: ∠AOB and ∠BOC; ∠BOC and ∠COD; ∠COD and ∠DOA Adjacent angles share a common vertex and side. 2. Two pairs of complementary angles: ∠AOB and ∠COD; ∠BOC and ∠DOA Complementary angles add up to 90 degrees. 3. Three pairs of vertical angles: ∠AOB and ∠COD; ∠BOC and ∠DOA Vertical angles are opposite angles formed by intersecting lines. They are always equal. 4. Two linear pairs: ∠AOB and ∠BOC; ∠BOC and ∠COD A linear pair is a pair of adjacent angles whose non-common sides form a straight line. They are always supplementary (add up to 180 degrees). 5. One pair of supplementary angles: ∠AOB and ∠BOC Supplementary angles add up to 180 degrees. Many other pairs of angles in the diagram are also supplementary.
