A bar magnet always aligns along the same line because it responds to the Earth’s magnetic field. Its poles orient themselves along the Earth’s north-south magnetic axis. Class 6 NCERT Chapter 4 Exploring Magnets NCERT Textbook Curiosity Science Session 2024-2025.
Yes, a circle has infinite rotational symmetry because it looks identical at any angle of rotation. There is no specific angle; every rotation maintains the circle’s symmetry, making its order infinite. class 6 Mathematics Textbook Chapter 9 question answer class 6 Mathematics ...
A square has four angles of rotational symmetry: 90°, 180°, 270°, and 360°. These angles represent the rotation at which the square looks identical to its original position, demonstrating its high symmetry order. class 6 Mathematics Textbook Chapter 9 question answer class ...
The order of rotational symmetry is determined by counting how many times a shape matches its original position during a full 360° rotation. Each matching position represents one instance of symmetry. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class 6 Mathematics ...
