True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
A triangle can have two obtuse interior angles true or false?
False
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
Is it true or false supplementary angles are always linear pairs?
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.
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
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
How determine whether the conjecture is true or false. If false give a counterexample. Given LMN and XMZ are coplanar. Conjecture The angles are vertical angles.?
Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
Does every hexagon have 6 obtuse angles true or false?
It's very difficult to answer a yes/no question with 'true' or 'false'.A regular hexagon has 6 obtuse interior angles.A hexagon that's not regular can have fewer than 6 .
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
If two angles form a linear pair then they are complementary true or false?
A linear pair are always supplementary, 180 degrees not 90.
Is it true that only 3 angles can be supplementary?
No. Any angles which add up to 180 degrees are supplementary.
