Exemplars (from the NaCCA curriculum)
E.g. 1. Draw an enlargement of shapes using a given scale factor. i. State the single transformation that maps triangle P onto Q. ii. State the single transformation that maps triangle P onto R.
iii. Investigate the characteristics of enlargements under the following conditions of scale factor: • if the scale factor (K) is negative • if the scale factor (K) is greater than 1 or less than -1 • if the scale factor (K) is between -1 and 1 (i.e., fraction) E.g. 2. Using an object, and its image, determine the scale factor in a transformation?
