Prove geometric theorems using coordinate geometry. Convert shapes to algebraic expressions, use distance formula, midpoint formula, and slope calculations. Triggers on "prove using coordinates", "analytic geometry", "distance formula", "show collinear", "prove perpendicular", "prove parallel"
Prove identities or existence using combinatorial counting - double counting, bijections, inclusion-exclusion. Triggers on "count", "number of ways", "how many", "bijection", "one-to-one correspondence", "combinatorial proof"

Convert an informal mathematical proof into verified Lean 4 code. Triggers on "formalize", "convert to Lean", "make rigorous", "verify this proof", or when user pastes informal proof text
