Question 2 - Page 235 Consider a figure with radial arms having exactly 7 angles of symmetry. What will be its smallest angle of symmetry? Is the number of degrees a whole number in this case? If not, express it as a mixed fraction. Let us find the angles of symmetry for other kinds of figures.For 7 angles of symmetry We divide 360° by 7 Angle of symmetry = (𝟑𝟔𝟎° )/𝟕 Now, let’s express this as a mixed fraction Thus, Angle of symmetry = (360° )/7 = 𝟓𝟏 𝟑/𝟕° Thus, the smallest angle of symmetry is not a whole number
