Karnataka State Syllabus Class 7 Maths Chapter 14 Symmetry Ex 14.2<\/h2>\n

Question 1.
\nWhich of the following figures have rotational symmetry of order more than 1:
\nSolution:
\n\"KSEEB
\n(a), (b), (d), (e), and (f) because these objects look exactly the same more than 1 number of times in a complete turn.<\/p>\n

Question 2.
\nGive the order of rotational symmetry for each figure :
\nSolution:
\n\"KSEEB
\nfig a has order 2
\na) This object while rotating at two positions 180\u00b0 and 360\u00b0 it looks exactly the same. Therefore it has rotational symmetry of order 2.<\/p>\n

b) This object in full turn, these are two positions 180\u00b0 and 360\u00b0 it looks exactly the same. Therefore it has rotational symmetry of order 2.
\n\"KSEEB
\nfig b has order 2<\/p>\n

\"KSEEB<\/p>\n

c) This object while rotating there are three positions 120\u00b0 and 240\u00b0 and 360\u00b0 the object looks exactly the same. Therefore it has rotational symmetry of order 3. fig c has order 3
\n\"KSEEB<\/p>\n

d) In full turn, this object will rotate and three are four positions such as 90\u00b0, 180\u00b0 270\u00b0, and 360\u00b0 the figure looks exactly the same. Therefore it has rotational symmetry of order 4.
\n\"KSEEB<\/p>\n

e) In a full turn, this object will rotate and there are four positions such as 90\u00b0, 180\u00b0 270\u00b0, and 360\u00b0, the figure looks exactly the same. Therefore it has rotational symmetry of order 4.
\n\"KSEEB
\nfig e has order 4<\/p>\n

f) The figure is a regular pentagon. In a full turn are five positions at 72\u00b0, 144\u00b0, 216\u00b0, 288\u00b0, and 360\u00b0 the figure looks exactly the same. Therefore it has rotational symmetry of order 5.
\n\"\"
\nfig f has order 5<\/p>\n

\"KSEEB<\/p>\n

g) In a full turn, there are 6 positions. i.e., 60\u00b0, 120\u00b0, 180\u00b0, 240\u00b0, 300\u00b0, and 360\u00b0 the figure looks exactly the same. Therefore it has rotational symmetry of order 6.
\n\"KSEEB
\nfig g has order 6<\/p>\n

h) This figure while rotating there are 3 positions the figure looks exactly the same at 120\u00b0, 240\u00b0, and 360\u00b0. Therefore it has rotational symmetry of order 3.
