Is it possible for a triangle to be both obtuse and a scalene?
yes
Is it possible for one triangle to be both an obtuse and scalene?
Yes. A scalene triangle is one in which all sides and angles are different. An obtuse triangle is one in which the largest angle is greater than 90o. An example of an obtuse scalene triangle would be one with angles 100o, 50o & 30o.
Can a triangle be both obtuse and scalene?
Yes.eg The triangle with sides 7 cm, 8 cm, 13 cm is both obtuse (angle opposite side of 13 cm is 120o) and scalene (none of the sides are equal).
Is it possible for an obtuse angle to have both a complement and a supplement?
Yes, but its complement is negative.
Can a triangle be both acute and obtuse?
No, because if there is on obtuse angle the triangle will always be obtuse.

Is it possible for one triangle to be both an obtuse and scalene?

Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
Is it possible for an obtuse angle to have both a complement and a supplement?
Yes, but its complement is negative.
Can a triangle be both acute and obtuse?
No, because if there is on obtuse angle the triangle will always be obtuse.
What is the supplement of an obtuse angle?
An obtuse angle is one over 90 degrees. If you are looking for the supplement it means that both angles have to equal 180 degrees. So the supplement of an obtuse angle would be an acute angle.
Is it possible for a triangle to have both a right angle and an obtuse angle?
No. An "obtuse" angle is greater than 90 degrees. (An angle of less than 90 degrees is an "acute" angle.) Since a Right angle is a 90 degree angle, there is no way to have another angle in the triangle that is "obtuse", because then the sum of the first TWO angles would equal more than 180 degrees. The sum of all THREE angles in a triangle sum exactly 180 degrees.
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
Can an angle be both obtuse and isosceles true or false?
False
Why can't an obtuse triangle not have a right angle?
Because an obtuse angle is greater than 90 degrees by definition and a right angle is 90 degrees by definition, so an obtuse triangle would need to have both a right angle and an obtuse angle, which would exceed the number of degrees than a triangle can have, which is 180 degrees.
