Exercise 14.2<\/h2>\n

Question 1.
\nWhich of the following figures have rotational symmetry of order more than 1:
\n\"NCERT
\nAnswer:
\nThe figures (a), (b), (d), (e) and (f) have rotational symmetry of order more than 1.<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nGive the order of rotational symmetry for each figure:
\n\"NCERT
\nAnswer:
\n(a) \u2192 2
\n(b) \u2192 2
\n(c) \u2192 3
\n(d) \u2192 4
\n(e) \u2192 4
\n(f) \u2192 5
\n(g) \u2192 6
\n(h) \u2192 3
\nExplanation
\n\"NCERT
\nLet us mark a point P as show in the figure (i) it requires two rotations each though 180\u00b0 about the point (x) to come back to its original position.
\n\u2234 It has a rotational symmetry of order 2.<\/p>\n

\"NCERT
\nMark a point P as shown in figure (i). It requires two rotations, each through an angle of 180\u00b0 about the marked point (x) to come back to its original position.
\nThus, it has a rotational symmetry of order 2.<\/p>\n

(c) Mark a P as shown in figure (i). It requires three rotations each through an angle of 120\u00b0 about the marked point (x) to come back to its original position.
\nThus, it has a rotational symmetry of order 3.
\n\"NCERT<\/p>\n

\"NCERT<\/p>\n

(d) Mark a point P as shown in the figure. It requires four rotations, each through an angle of
\n900 about the marked point (x) to come back to its original position.
\nThus it has a rotational symmetry of order 4.
\n\"NCERT<\/p>\n

(e) The figure requires four rotations each of 90\u00b0, about the marked point (x) to come back to its original position.
\n\u2234 It has a rotational symmetry of order 4.<\/p>\n

(f) The figure is a regular pentagon. It requires five rotations, each though an angle of 72\u00b0 about the marked point to come back to its original position.
\n\u2234 It has rotational symmetry of order 5.<\/p>\n

(g) The given figure requires six rotations, each though angle of 60\u00b0; about the marked point (x) to come back to its original position.
\n\u2234 Thus, it has a rotational symmetry of order 6.<\/p>\n

(h) The given figure requires three rotations each through an angle of 120\u00b0, about the marked point (x) to come back to its original position.
\n\u2234 It has a rotational symmetry of order 3.<\/p>\n","protected":false},"excerpt":{"rendered":"
