6. Worked Examples (3 short problems with lemma-focused solutions)

• Example 1: Use Angle Bisector + Stewart to find cevian length.
• Example 2: Show concurrency using Trig Ceva and isogonal conjugates.
• Example 3: Solve a cyclic quadrilateral length problem via Ptolemy.

2.4 Ceva’s Theorem (and Trig Ceva)

• Statement: For cevians from A,B,C meeting opposite sides at D,E,F, concurrency ⇔ (BD/DC)(CE/EA)(AF/FB)=1. Trig version uses sines.
• Sketch: Ratios from similar triangles.
• Uses: concurrency proofs, constructing cevians.
