After rotating by 45 degree about the centre, a figure looks exactly the same as its original position.At what angle will the figure look exactly the same? What if the angle is 50 degree or 60 degree?
(Please answer it only experts).
Dear student ,
the figure looks exactly same after rotating about 45° .
=> The figure will look exactly the same if angle of rotation is a multiple of 45°.
I.e , angle = 45× n , where n is an integer .
Such angles are , 0° , 90° , 135° , 180°, 225° and so on .
Since 50° and 60° are not multiples of 45° , figure will not look exactly same .
