Answer
Hint: Rotational symmetry is the property a shape has when it looks the same after some rotation by a partial turn. Line symmetry is a type of symmetry with respect to reflection. Thus, in the question, we have to basically draw those figures which when rotated through an angle (less than\[{{360}^{o}}\]) looks exactly the same as the figure in original form and they should also have symmetry with respect to the axis passing through them. So, let us start the solution of the above question.Complete step-by-step answer:So, now we will start drawing the figures which have both rotational and line symmetry. So our first figure is an equilateral triangle: -
