Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
All supplementary angles do not form a linear pair. The opposite angles of any quadrilateral inscribed in a circle (a cyclic quadrilateral) are supplementary but they are not a linear pair. However, all linear pair are supplementary.
If they do , the angles are supplementary !
No, angles that form a linear pair are supplementary.
Yes.
supplementary
No, intersecting lines form four pairs of supplementary angles
yes
Yes, they will always form a linear pair because supplementary means 180 degrees.
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
Yes.
