<h2>Lesson Plan</h2>

[Contributor - Kripa S]



'''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
