Objective: Learn more on similarity in patterns, lines of symmetry, rotational symmetry
Subtopics to be covered:
- patterns with lines of symmetry
- patterms with mirror reflection
- patterns with rotational symmetry, find angle of rotation, order of rotational symmetry
Learning Outcome:
- Students can identify the lines of symmetry for a given figure
- They can identify if the figure has mirror reflection
- They can identify is an object show rotational symmetry and tel the order of the same
