Is a right angle and an obtuse angle always supplementary?
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.
Is one obtuse angle and one right angle supplementary?
no
Every pair of supplementary angles includes one obtuse angle?
Every pair of supplementary angles includes one obtuse angle?
If angles are supplementary then one of the angles is an obtuse angle?
No. Both could be right angles.
Does a pair of supplementary angles include a obtuse angle and an acute angle?
Yes, unless they are both right angles.
What are the types of geometric angles?
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
Does a triangle sometimes always or never have a right triangle and an obtuse triangle?
A triangle can never include a right angle and an obtuse angle together in it.
If angles are supplementary then one of the angles is an obtuse angle.?
Yes, but not always because 2 right angles would also be supplementary adding to 180 degrees.
What is a rectangle is it a right angle acute or obtuse?
its a right angle
If angle a and b are complementary and angles c and d are supplementary then d is what angle?
It can have any value in the range (0, 180) so it can be acute, right or obtuse.
Does an right angle have an obtuse angle?
First: A right angle is an angle of 90 degrees Second: An obtuse angle is an angle of 91 degrees to 179 degrees A right angle can not have an obtuse angle
Can two obtuse angle be supplementary angle?
It is not possable for two obtuse angles to be supplementary. This is because an obtuse angle is an angle greater than 90 degrees but less than 180 degrees while a supplementary angle is an angle which, when added to an existing angle will sum to 180 degrees. This can be explained mathematically, If A + B ≠ 180 where A and B are both obtuse. In this equation, there are constraints on both variables in this equation. These are, a). A + B ≠ 180 b). 180 > A > 90 c). 180 > B > 90 If we look at (90 + ∞-1) + (90 + ∞-1) you do not get 180, which would mean that two obtuse numbers could be supplementary, but you get 180 + 2∞-1 which by definition is An angle larger than two right angles but less than a full circle (between 180° and 360°" - see http://en.wikipedia.org/wiki/Reflex_angle#Types_of_angles
