False
Angles that have a common side between them and a common vertex are called adjacent angles.
adjacent
If two angles do not have a common vertex they cannot be adjacent angles.
Alternate angles
Adjacent angles
No because two angles do not have common vertex
Those are a pair of 'supplementary' angles.
Angles that have a common side between them and a common vertex are called adjacent angles.
Supplementary angles.
A possibility is the interior and exterior vertex angles add up to 180 degrees which are supplementary angles * * * * * On the basis of the information given in the question, they are simply adjacent angles.
Adjacent Angles
adjacent
Adjacent angles have a common side and a common vertex.
If two angles do not have a common vertex they cannot be adjacent angles.
Alternate angles
Adjacent angles.
