A point indicates a precise location with no length, width, or height. Examples include the tip of a needle, the sharpened end of a pencil, and the pointed end of a compass. Class 6 NCERT Ganita Prakash Chapter 2 Lines and ...
Supplementary angles are two angles whose sum is 180°. For example, ∠AOB = 120° and ∠BOC = 60° are supplementary, as their total is 180°. They are often used in linear pairs. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
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 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 ...
Use a protractor to measure ∠BXE, ∠CXE, ∠AXB, and ∠BXC. Align the protractor at the vertex (X), measuring each angle carefully. Record the degree value of each angle for accurate representation and understanding. class 6 Mathematics Textbook Chapter 2 question answer 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 ...
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 ...
∠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 ...
