class 6 Mathematics Textbook Chapter 2 question answer
The terms “acute” and “obtuse” align with their visual characteristics. Acute angles are sharp and pointed, as their arms converge quickly at a small angle. Obtuse angles are broader and appear blunt, with their arms forming a wide opening. These descriptive terms help to intuitively relate the appearance of angles to their respective names, simplifying their recognition and understanding in both mathematical and everyday contexts.
