Concepts The movement of shapes and objects can be described using simple words such as flip, turn and slide. A shape’s position, orientation or size can be changed without changing the kind of shape it is. Transformations involve actions on shapes. The mathematical terms reflect, rotate and translate can be used to describe the movement of shapes and objects. A shape or line is reflected when it is the same perpendicular distance from the mirror line. A shape or line is rotated when it is turned around a point. A shape or line is translated when it is moved a certain distance from its original position (without turning). Simple units of measurement and/or grids are useful to describe and plot shape movements. A shape or pattern has reflective symmetry if it remains the same when reflected through a mirror line. The mirror line can be part of the shape/object or external to it. A shape or line is rotated when it is turned around a point called the centre of rotation. The direction and amount of turn can be described used mathematical terminology and angle measures. A shape or pattern has rotational symmetry if it looks the same after a rotation of less than one full turn. Tessellation involves covering a surface with no gaps or overlaps, using one or more geometric shapes. Certain shapes and combinations of shapes can tessellate. Regular tessellations are tessellations of regular polygons. There are three types of regular tessellations: triangles, squares and hexagons. Transformations can involve a number of steps. These steps can be identified, ordered, recorded and performed (with or without technology). Co-ordinates are pairs of numbers, the first of which indicates the point on the x-axis and the second on the y-axis. When shapes are transformed on the co-ordinate plane, their co-ordinates can be predicted and deduced. It is possible to enlarge a shape. Enlarged shapes remain similar to the original shape in terms of their corresponding angles and the proportion of their sides.
