A straight angle measures 180°, representing half of a 360° full turn. A right angle measures 90°, which is half of a straight angle. These are key geometric references for angle classification. Class 6 NCERT Ganita Prakash Chapter 2 Lines and ...
“Acute” angles are sharp because their arms meet quickly, forming a small angle. “Obtuse” angles are blunt due to their wider opening, creating a less pointed shape, resembling their linguistic meanings. Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles class ...
Acute angles measure less than 90°, and obtuse angles measure between 90° and 180°. Draw examples like 45° and 30° for acute, and 120° and 150° for obtuse, in varying directions to showcase versatility. Class 6 Mathematics Chapter 2 Lines and ...
Only one unique line can pass through any two distinct points. This is a fundamental property of geometry where two points determine a straight line, connecting them directly and uniquely. Class 6 Mathematics Ganita Prakash Lines and Angles Class 6 Mathematics Chapter ...
