Use a protractor to measure angles in windows, doors, desks, and corners. Common angles include right angles (90°) at corners, acute angles in slanted objects, and obtuse angles where openings exceed 90°. Class 6 NCERT Ganita Prakash Chapter 2 Lines and ...
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 ...
Acute angles are smaller than 90°, right angles measure exactly 90°, obtuse angles range between 90° and 180°, and straight angles equal 180°. Identify these based on their degree measurements in the figures. Class 6 Mathematics Chapter 2 Lines and Angles ...
Classroom windows often form multiple right angles at corners, typically four per rectangular window. Additional right angles exist in door frames, blackboard edges, desks, and other rectangular or perpendicular structures within the room. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
Folding creates angles between the fold and paper edges. Use a protractor to measure them. Different folds produce angles of varying sizes, the largest being obtuse or straight and the smallest acute. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
Label the angles using points on their arms and their vertex, e.g., ∠ABC. Compare by superimposing the angles, aligning their vertices and one arm. Alternatively, use a protractor to measure and compare their degrees. class 6 Mathematics Textbook Chapter 2 question ...
∠APC cannot be labeled as ∠P because the vertex P has multiple angles meeting there. To avoid ambiguity, angles must include points on the arms, ensuring clarity about which angle is referred to. Class 6 NCERT Ganita Prakash Chapter 2 Lines ...
Yes, angles are created by the rotation of one arm relative to a fixed arm. The degree of this rotation determines the size of the angle, ranging from acute to reflex. Class 6 Mathematics Chapter 2 Lines and Angles question answer Class ...
