Two angles[1] are Adjacent when they have a common side and a common vertex (corner point), and dont overlap.
Angle ABC is adjacent to angle CBD
Because:
they have a common side (line CB) they have a common vertex (point B) What Is and Isnt an Adjacent AngleAdjacent Angles
they share a vertex and a side
NOT Adjacent Angles
they only share a vertex, not a side
NOT Adjacent Angles
they only share a side, not a vertex
Dont Overlap!ALSO the angles must not overlap.
NOT Adjacent Angles
angles a and b overlap
