Either an isosceles or a scalene triangle can have one right angle.
An isosceles triangle can never be a scalene triangle but it can take the shape of a right angle triangle
A scalene right triangle is a triangle that has no congruent sides and and one right angle.
It is: 180-interior angle = exterior angle
180 minus interior angle = exterior angle
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.
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
If you meant scalene triangle, then it may have a right angle. By definition, a scalene triangle is a triangle with no angle or side measures that are the same. For example, a 30,60,90 triangle is scalene.
Either an isosceles or a scalene triangle can have one right angle.
A Scalene triangle does not have a right angle because the triangle is all different angles so...
An isosceles triangle can never be a scalene triangle but it can take the shape of a right angle triangle
A scalene triangle has no equal sides and no right angle.
Three angle and three sides that are closed is a triangle. interior angles add up to 180 exterior anglis add up to 900

It is impossible to have an obtuse AND scalene triangle, because in order for it to be obtuse, it must have one obtuse angle but, in order for a triangle to be scalene it must have two equivalent sides. So, in the end if you have an obtuse and scalene triangle, it is not longer a triangle.
