Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.

No not all obtuse triangular are similar. :)

Of course not! There are obtuse and acute triangles.

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.

No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.

No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.

An obtuse triangle

No, because they only have the limitations of 91 degrees (lowest obtuse angle) and 179 degrees (highest obtuse angle). Two obtuse angles could be either of them or anything in between.

-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.

they are both angkes

No. Scalene triangles have no equal sides or angles but can be obtuse, right angled or acute.

Triangles may be right triangles equilateral triangles acute or obtuse triangles
