Measure ∠PQR, ∠PQS, and ∠PQT using a protractor. Align it with the vertex (Q) and the respective arms. Note the intersection points on the protractor scale and record the degree values systematically. Class 6 Mathematics Chapter 2 Lines and Angles question ...
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 ...
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 ...
Use a paper protractor to measure the given angles. Ensure alignment of the protractor’s center with the vertex and zero-mark with one arm. Read the angle measurement accurately from the scale. class 6 Mathematics Textbook Chapter 2 question answer class 6 Mathematics ...
Use a protractor to measure angles in windows, doors, desks, and corners. Common angles include right angles (90°) at corners, acute angles in slanted objects, and obtuse angles where openings exceed 90°. Class 6 NCERT Ganita Prakash Chapter 2 Lines and ...
Dividing a circle into equal parts yields angles based on the formula 360°/n. For 1, 2, 3, 4, 5, 6, 8, 9, 10, and 12 parts, the angles are 360°, 180°, 120°, 90°, etc. Class 6 NCERT Ganita Prakash Chapter 2 ...
A straight angle measures 180°, representing half of a 360° full turn. A right angle measures 90°, which is half of a straight angle. These are key geometric references for angle classification. Class 6 NCERT Ganita Prakash Chapter 2 Lines and ...
“Acute” angles are sharp because their arms meet quickly, forming a small angle. “Obtuse” angles are blunt due to their wider opening, creating a less pointed shape, resembling their linguistic meanings. Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles 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 ...
