Adjacent Angles

Subject: Geometry definitions

I appreciate your answering my question. The question says to define 
"adjacent angles."  We're learning about linear pairs in my class and 
I think it has something to do with those.

Hi Dave - thanks for writing to Dr. Math.

Adjacent angles are angles that share a vertex and a common side 
between them, but have no interior points in common. In the diagram 
shown below, angles ADB and BDC are adjacent angles.

        A       B       C
         \      |      /
          \     |     / 
           \    |    /
            \   |   /
             \  |  /
