The centre of rotation in GCSE Maths refers to the fixed point around which a shape is rotated, or turned, in a plane. When performing a rotation transformation, every point of the shape moves in a circular path around the centre of rotation, maintaining a constant distance from this point while changing its position and orientation. The rotation is defined by the angle of rotation, which indicates how far, typically in degrees, the shape is turned clockwise or anticlockwise. Understanding the centre of rotation helps in accurately describing and predicting the new position of the shape after the rotation is applied.
