Answer:

\huge\boxed{\fcolorbox{pink}{crimson}{AnSwEr:-}}

they have a common vertex (O).

they have a common arm (OB) and the other arms OA and OC of the two angles are on opposite sides of the common arm OB.

Yes, ∠BOC is adjacent to ∠BOA

NO ,  ∠BOC is not adjacent to ∠COB

Given:

  • A common point O
  • Rays OA , OB and OC
  • Ray OB is in between Rays OA and OC

To Find:

  • Is ∠BOC adjacent to ∠BOA
  • Is ∠BOC adjacent  to ∠COB

Solution:

Angles that have a common vertex and a common side are called adjacent angles.

The angles must not overlap.

∠BOC and ∠BOA have common vertex O and a common side OB

Hence These are adjacent angles.

Yes, ∠BOC is adjacent to ∠BOA

∠BOC and ∠COB have common vertex O and  common side OB  and OC

Hence These are Overlapping angles.

As angles are overlapping so these are not adjacent angles.

NO ,  ∠BOC is not adjacent to ∠COB

(correction in Question ∆ symbol should have been ∠ )

Yes, ∠BOC is adjacent to ∠BOA

NO ,  ∠BOC is not adjacent to ∠COB
