Angles are classified as acute (<90°), right (90°), obtuse (90°–180°), straight (180°), and reflex (>180° but <360°). Examples include a 45° acute angle, a 120° obtuse angle, and a 270° reflex angle. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...

A right angle measures exactly 90° and forms an “L” shape. It is unique as it represents perpendicularity, unlike acute (<90°), obtuse (90°–180°), or reflex (>180°) angles, which indicate different rotational measures. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
A straight angle measures exactly 180°, representing half a complete turn. It forms a straight line with arms extending opposite each other. Examples include a folded book’s spine or the horizon’s line. Class 6 Mathematics Ganita Prakash Lines and Angles Class 6 ...
A straight angle measures 180° and equals two right angles. Dividing a straight angle into two equal parts results in two right angles, each measuring 90°, often seen in linear or perpendicular geometry. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
