Question 5 In a figure, 60° is an angle of symmetry. The figure has two angles of symmetry less than 60°. What is its smallest angle of symmetry?Since figure has two angles of symmetry less than 60° It means 60° is the 3rd angle of symmetry So, we write 60° = 3 × Smallest Angle of symmetry (60° )/3 = Smallest Angle of symmetry 20° = Smallest Angle of symmetry Smallest Angle of symmetry = 20° Thus, smallest angle of symmetry is 20°
