No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
Yes, that works for any triangle. The height always has to be at a right angle to the base. If there is an angle over 90 degrees, you may have to extend the base.Yes, that works for any triangle.

Because the 3 angles in a right angle triangle add up to 180 degrees and if an obtuse angle was included then they would add up to over 189 degrees.
It is a scalene triangle (no sides or angles equal) with one obtuse angle meaning over 90 degrees.
Because all the angles of a triangle add up to 180. If you have two angles that are greater that 90, then you are already over 180 and don't have room to fit another angle in.Because the 3 interior angles of a triangle add up to 180 degrees and the sum of 2 obtuse angles would be over 180 degrees
