Objective: To introduce congruency and similarity of figures

Subtopics to be covered:

- What is congruency, what is similarity

- Identify congruent or similar figures in given set of figures

- Ratio to define the similarity of figures

- Symmetry ( mirror, rotational, point)

Learning Outcome:

- Students can identify congruent shapes and similar shapes

- Students can tell the ratio of change for similar shapes

- Students can identify the type of symmetry for a given shape
