Every pair of supplementary angles includes one obtuse angle?
Angles larger than a right angle and smaller than two right angles (between 90° and 180°) are called obtuse angles("obtuse" meaning "blunt").
No, they cannot.
Two angles are adjacent if they have the same vertex, share a side and do not overlap. It is, therefore, perfectly possible for two obtuse angles to be adjacent. In fact, every pair of adjacent angles in a hexagonal tessellation (a honeycomb, for example), consists of a pair of obtuse angles (120 degrees).
Yes if they are right angles
Because they are obtuse angles!
No
Only if you add them it is possible but not by themselves
Vertical angles can be either acute, obtuse, or right, depending on the measures of the angles formed by the intersecting lines. If the angles measure less than 90 degrees, they are acute. However, if they measure more than 90 degrees, they are obtuse. Therefore, a pair of vertical angles can be acute, but this is not always the case.
name two obtuse vertical angles.
they can be obtuse say ther are two lines intersecting two of the angles are acute (50degrees) that means the other pair must be obtuse 180-50=130 so the other two angles are obtuse with a measurement of 130degrees
Vertical angles are, by definition, equal. So if one is obtuse then so is the other.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
