Which angle(s) are adjacent to ∠DOC ?

1 answer

To determine which angles are adjacent to ∠DOC, we need to understand the orientation of the points A, B, C, D, and E around the point O.

From the description, since A, O, and E are collinear (falling on a straight line), we can infer that:

  • ∠AOB and ∠BOC would be adjacent to ∠DOC, as they share a common ray OB.
  • Additionally, ∠DOD is also adjacent to ∠DOC, sharing the common ray OD.

So, the angles adjacent to ∠DOC are ∠AOB, ∠BOC, and ∠DOA.
