That is correct.
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.
no
Every pair of supplementary angles includes one obtuse angle?
No. Both could be right angles.
Yes, unless they are both right angles.
A triangle can never include a right angle and an obtuse angle together in it.
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
Yes, but not always because 2 right angles would also be supplementary adding to 180 degrees.
its a right angle
It can have any value in the range (0, 180) so it can be acute, right or obtuse.
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
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
