What is a triangle?
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.
Since the triangle is a scalene triangle, all the sides of the given polynomial can not be equal. Therefore, it can not be a rhombus or a square.
Also, it is given that the triangle is an obtuse triangle therefore, there will be no angle with a 90° measurement. Thus, it can not be a rectangle.
Hence, the correct option is A.
