Rotating Shapes
π¬ Video Tutorial
(0:01) What is Rotation?: Rotation is a transformation that turns a shape around a fixed point (called the centre of rotation), either clockwise or anticlockwise, by a specific angle (called the angle of rotation).(0:56) Rotating Shapes Using Tracing Paper: Place tracing paper over the shape, fix it at the center of rotation, trace the shape, then rotate the paper by the required angle. Mark the new points and connect them to get the rotated shape.(1:40) Rotating Shapes by Drawing Line:For each vertex, draw a line to the centre of rotation, measure its length, then rotate the line segment by the required angle. Mark the new position and connect all points to form the rotated shape.(2:28) How to Find the Centre of Rotation: Draw perpendicular bisectors between corresponding points of the original and rotated shapes. The intersection of the bisectors is the centre of rotation.
