Give the order of rotational symmetry for each of the following figures when rotated about the marked point (x): |
|
Answer» (i) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 4. (ii) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 3. (iii) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 3. (iv) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 4. (v) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 2. (vi) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 4. (vii) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 5. (viii) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 6. (ix) A figure is said to have rotational symmetry if its fits onto itself more than once during a full turn that is rotation through 360° Therefore the given figure has its rotational symmetry as 3. |
