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 ...
