Angles are classified as acute (<90°), right (90°), obtuse (90°–180°), straight (180°), and reflex (>180° but <360°). Each type reflects a specific range of rotation between the angle’s arms. Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles class 6 Mathematics ...
An angle is formed by two rays sharing a common endpoint. The rays are called arms, and the common point is called the vertex. For example, ∠ABC has arms BA and BC with vertex B. Class 6 NCERT Ganita Prakash Chapter ...
Measure each angle with a protractor. Classify ∠PTR, ∠PTQ, and ∠WTP as acute (<90°), obtuse (90°–180°), right (90°), or reflex (>180°) based on their measurements. Record results for accuracy. Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles class 6 Mathematics ...
Draw each angle by aligning the protractor’s center with the vertex. Mark the required degree on the scale, join the vertex with the mark, and label the angles. Ensure accuracy for each measurement. Class 6 NCERT Ganita Prakash Chapter 2 Lines ...
