No.The definition of an oblique triangle is "any triangle that is not a right triangle".
No. An isosceles triangle has, by definition, two sides of equal length. A scalene triangle has, by definition, no sides of equal length. So, by definition (and the fact that 0 is not 2), an isosceles triangle cannot be scalene.

By definition, a triangle has three sides.
a triangle that contains an obtuse interior angle
A triangle with 3 equal sides and angles.
Absolutely false. A scalene triangle by definition has no side equal to another. An isosceles triangle by definition has two equal sides.
There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.
isosceles triangle is a 3-sides triangle
No it cannot. A triangle is by definition a three sided shape.
