2. determine the properties of reflection in different situations
3. draw an image given an object and a mirror line on plane surface and Cartesian plane
4. determine the equation of the mirror line given an object and its image
5. carry out congruence tests for triangles
6. promote use of reflection and congruence in real-life situations
