Is it true that only 3 angles can be supplementary?
No. Any angles which add up to 180 degrees are supplementary.
Supplementary angles add to 270 degrees true or false?
False. Supplementary angles add to 180degrees.
Is a square the conseutive angles are supplementary?
True
Is true the supplementary angles are always adjacent?
Sometimes but not always depending on what type of polygon it is and supplementary angles add up to 180 degrees
Two base angles of a trapezoid are ' ' supplementary?
'never'
What are all of the situations in which the statement Two vertical angles are supplementary is true?
If the lines are perpindicular then each pair of vertical angles are supplementary
Are two acute angles sometimes supplementary?
No,never
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
If consecutive angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
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.
Are vertical angles alway sometimes or never supplementary?
sometimes
If two congruent angles form a supplementary they are acute angles.?
Not true because supplementary angles add up to 180 degrees and two acute angles would be less than 180 degrees.
