The angle of rotation is the smallest angle a shape is turned to make it look the same With rotational symmetry, a shape can be rotated (turned) and still look the same. The hexagon looks the same 6 times when turned 360 degrees This hexagon has an ORDER OF ROTATION of 6 This hexagon has an angle of rotation of 60 The hexagon looks the same after a 60 turn. ∘ ∘ To calculate the ANGLE of rotation divide 360 by the ORDER of rotation 360 6 = 60 ∘ How many degrees must the figure turn to look the same? (angle of rotation) How many times will this figure look the same after a 360 degree turn? (order of rotation) ∘ Calculate angle of rotation by dividing 360 by 2 The figure to the left has an order of rotation of It will look the same twice when you turn the figure 360 degrees. 360 2 = ∘ 2 Calculate angle of rotation by dividing 360 by 3 The figure to the left has an order of rotation of It will look the same thrice when you turn the figure 360 degrees 360 3 = ∘ 3 Calculate angle of rotation by dividing 360 by 1 This figure has an order of rotation of ONE. 360 1 = ∘ ORDER of rotation Divide 360 by the ORDER of rotation to find the of rotation. ANGLE 360 ORDER of rotation Divide 360 by the ORDER of rotation to find the of rotation. ANGLE 360 5 = Angle of rotation ∘ ORDER of rotation Divide 360 by the ORDER of rotation to find the of rotation. ANGLE 360 = ORDER of rotation Divide 360 by the ORDER of rotation to find the of rotation. ANGLE 360 2 = Angle of rotation ∘ ORDER of rotation Divide 360 by the ORDER of rotation to find the of rotation.
