Geometry Art - Walt: use the invariant properties of figures and objects under transformation (reflection-whakaata, rotation-hurihanga, translation-nekehanga, or enlargement).
We learned that the invariant properties included internal angles, area, basic shape. When a shape is rotated the lengths, area and angles within the shape do not change but the orientation/position of the shape does. When a shape is reflected the lengths, area and angles within the shape do not change but the orientation/position of the shape does. When a shape is translated lengths, area, angles and orientation/position do not change. When a shape is enlarged (or reduced) by a scale factor angles and orientation do not change but area and lengths do.
