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 question answer
Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles
Acute angles are less than 90°, easily recognized by their sharp appearance. Right angles measure exactly 90°, often forming perpendicular lines. Obtuse angles, larger than 90° but smaller than 180°, appear blunt. Straight angles, measuring 180°, form a flat line. Observe the figures to classify each angle based on its size and shape, referencing their measurements or visual characteristics for precise identification.
