Acute angles are less than 90° (e.g., 45°), obtuse angles range between 90° and 180° (e.g., 120°), and reflex angles exceed 180° but are less than 360° (e.g., 270°). Class 6 Mathematics Ganita Prakash Lines and Angles Class 6 Mathematics Chapter 2 ...
The angle is less than 18°. Doubling, tripling, or quadrupling the angle must keep it below 90°. However, multiplying by 5 must exceed 90° but stay below 180°, so possible measures are 1°–17°. class 6 Mathematics Textbook Chapter 2 question answer class ...
Triangles can be classified by their angles as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°). These classifications help in understanding triangle properties and solving related problems. class 6 Mathematics Textbook Chapter 2 ...
Place the protractor’s center at the vertex and align one arm with the baseline. Read the measurement where the second arm intersects the scale, ensuring alignment for accuracy. Record the measured degree. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
Fold the paper diagonally to form a slanting crease. Open the paper, then fold it again such that the new fold meets the first crease at a 90-degree angle. Ensure edges align properly. Class 6 Mathematics Chapter 2 Lines and Angles ...
Superimposition is used in various fields, like comparing shapes in geometry, checking congruence in biology (e.g., bone structures), and aligning blueprints or mechanical parts for accuracy in engineering designs. class 6 Mathematics Textbook Chapter 2 question answer class 6 Mathematics Chapter 2 ...
To draw this angle, place point S as the vertex. Draw two rays, ST and SR, starting at S and extending in different directions. Label S as the vertex, and T and R on the arms. Class 6 Mathematics Chapter 2 ...
