Teaching guide
Design, create and test algorithms that decide whether shapes are congruent or similar, and describe how they work.
Write the test for congruence or similarity as an ordered set of checks (matching sides and angles), then run shapes through the algorithm and refine any step that fails.
Assuming shapes are similar just because they look alike, and leaving out a condition the test needs.
