Yes.
A right angle
No. In fact, they never are. A right angle by definition is 90 degrees. An obtuse angle is any degree greater than 90. In order for two angles to be supplementary, they must equal 180 degrees. Because an obtuse angle is always greater than 90 degrees, and a right angle is always 90 degrees, an obtuse angle and a right angle can never be supplementary.
A right angle.
Definition of a supplementary angle: an angle that is supplementary to another angle is an angle in which the sum of both angles forms a straight line or 180 degrees.Definition of a right angle: an angle whose measure is 90 degrees.Using these terms, let's put them into an equation.Right angle + Supplementary angle = 180.90 + Supplementary angle = 180.Subtract 90 from both sides.Supplementary angle = 180 - 90Supplementary angle = 90 degrees.Alternatively, you can think that two right angles are equivalent to a straight line and that all right angles are congruent and therefore; their supplementary angles are also congruent.
A right angle.
no
90 degrees.
That is correct.
2 right angles will form a supplementary angle of 180 degrees
It is another right angle of 90 degrees because supplementary angles add up to 180 degrees.
Every pair of supplementary angles includes one obtuse angle?
One right angle is equal to 90 degrees, or a vertical line extending from the o degree plane. Therefore, two right angles, presumably side to side, would have 180 degrees, since together the would be supplementary angles. Supplementary angles are two angles which combine to from 180 degrees, and 90 plus 90 would equal 180 degrees. Look at angle DBE and at angle EBC. Each are 90 degree angles, or right angles, and together equal 180 degrees.
