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.
Depends on the quadrilateral. Eg in a cyclic Quad, opposite angles are supplementary. Note that it is impossible that there would be only one pair of supp. angles as the internal angles total 360o
Supplementary angles are any angles in which their degrees add to a sum of 180o. In the related links you will find an example of Supplementary angles.
Supplementary angles can have any number of angles as long as the angles add up to 180 degrees.
No. Any angles which add up to 180 degrees are supplementary.
Yes. Any two are supplementary.
All "parallelograms" have opposite sides that are parallel. If all four sides have an equal length and the angles are not all right angles, it is a rhombus. If there is any right angle, then they are all right angles and the parallelogram is a square.(note : it is not possible for a quadrilateral to have four equal sides without being one of these parallelograms.)
Any two angles whose measures add up to 180 degrees. For example, opposite angles of a cyclic quadrilateral (quadrilateral whose vertices are on a circle).
Any pair of adjacent angles.
Yes, any two angles in a parallelogram that share a common side are supplementary.
A pair of opposite angles. The sum of all four angles is 360 degrees. Any two adjacent angles are supplementary to each other and add up to 180 degrees
Any two angles which sum to 180o are called Supplementary Angles
