Is it true that isosceles triangles may be obtuse or acute but never right?
No, it is not true.
Is it true that an isosceles triangle can be acute or obtuse?
Yes, it is true that an isosceles triangle can be acute or obtuse. As long as a triangle has two equal angles and two equal sides, it is isosceles. That situation can occur in both acute (all angles less than 900) and obtuse (one angle more than 900) triangles. Examples are a triangle with the angles being 75-75-30 degrees (acute) and one having angles of 120-30-30 (obtuse). Of course the sides of the angles that are equal would also be equal, so both examples are of isosceles triangles.
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
Is it true that an obtuse triangle has two obtuse angles and one acute angle?
No
What is he sum of the angles of an obtuse triangle?
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
Isosceles triangles can be acute or obtuse true or false?
true
Is it false an obtuse triangle is never right?
It's true that an obtuse triangle is never right because obtuse triangles are bigger than right triangles, which are 90 degrees. Obtuse Triangles are always bigger than Right triangles(90 degrees) , so It is true.
Is it true that isosceles triangles may be obtuse or acute but never right?
No, it is not true.

Is it true that an obtuse triangle has two obtuse angles and one acute angle?
No
Is it true that an obtuse triangle can have a one acute triangle?
I assume that the second use of the word "triangle" in the question should be angle. An obtuse triangle must have two acute angles.
What is he sum of the angles of an obtuse triangle?
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
Does obtuse triangle have any angles congruent?
An obtuse triangle must have two acute angles and these can be congruent.
Is a triangle a figure formed by three segments connecting three noncollinear points?
This is a true statement that defines a triangle in geometry. However, there are many different types of triangles, such as obtuse, acute, scalene, right, equilateral, and isosceles triangles.
Is it true that a obtuse triangle has a greater area than any acute triangle?
Not at all.
What statement is always true about an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
