True only if the two angles are adjacent (i.e. have a point in common). By definition, supplementary angles add up to 180° therefore they are linear pairs, if they are adjacent.
Otherwise false. Imagine drawing an angle of 40° at the top of the page and another of 140° at the bottom. These angles are supplementary but not a linear pair.

If two angles form a linear pair then they are complementary true or false?
A linear pair are always supplementary, 180 degrees not 90.
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
Intersecting chords form a pair of supplementary vertical angles?
false
Two angles that have a common vertex and a common side are called supplementary angles. T or F?
False
If two angles form a linear pair then they are complementary true or false?
A linear pair are always supplementary, 180 degrees not 90.
Are Adjacent angles of a quadrilateral in a circumscribed circle are always supplementary?
False :]
Supplementary angles add to 270 degrees true or false?
False. Supplementary angles add to 180degrees.
Is this statement true or falseIf a quadrilateral is a parallelogram, then its opposite angles are always supplementary?
false
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
If a quadrilateral is a parallelogram then its opposite angles are always supplementary?
False because it will have 2 equal opposite obtuse angles and 2 equal opposite acute angles with the 4 angles adding up to 360 degrees.
Why is this conjecture false 'If two angles are supplementary then one of the angles must be obtuse'?
they could both be right angles
Intersecting chords form a pair of supplementary vertical angles?
false
Two angles that have a common vertex and a common side are called supplementary angles. T or F?
False
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
Can a exterior angle be found through the use of complementary angles?
false but You can find the measure of an exterior angle by using supplementary angles.
