![]() Translations are described by a vector, which tells us how many units up/down and left/right to move the shape.Įnlargement involves making a shape bigger or smaller. Translations involve moving a shape to a different position without changing its size or orientation. It is helpful to use tracing paper when doing rotations. ![]() ![]() When rotating shapes we need to know the centre of rotation (given as a coordinate), angle of rotation (given in degrees) and direction of rotation (either clockwise or anticlockwise). Rotations involve turning a shape around a point. Common lines used as a mirror line are the x axis, the y axis and the line y=x. In order to describe a reflection we need to describe or give the equation of the mirror line. Reflections use a mirror line and result in the shape being flipped. There are four types of transformation, reflection, rotation, translation and enlargement. A transformation is something which changes the position or size of an object.
