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 ...
Rotational symmetry occurs when a shape looks identical after being rotated about a central point by a specific angle. It can be identified by rotating the shape and checking if it overlaps with itself. Class 6 NCERT Ganita Prakash Chapter 9 ...
To test for a line of symmetry, fold the shape along a proposed line. If both halves overlap perfectly, the line is a symmetry axis. Alternatively, check if one half mirrors the other. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class ...
No, a rectangle’s diagonals are not lines of symmetry. While they divide the rectangle into triangles, the triangles are not identical or congruent due to differing lengths of adjacent sides, breaking symmetrical balance. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class ...
