The 13 pages that link to Menelaus's theorem, each with the reason it gives.

• Synthetic geometryBroader topic: It exemplifies how synthetic incidence arguments can establish precise relations in triangle configurations.

• CollinearityRelated: Its converse determines whether three side-intersection points are collinear.

• Ceva's theoremCompared with: It gives a related ratio test for collinearity rather than concurrence.

• Triangle geometryRelated: It provides a complementary ratio test for collinearity across a triangle.

• Miquel's theoremRelated: Like Miquel's theorem, it turns a geometric configuration into a concise condition.

• Simson lineRelated: Directed side ratios offer an algebraic route to proving the three feet are collinear.

• Intercept theoremCompared with: It handles a transversal crossing triangle sides without requiring a parallel line.

• Butterfly theoremRelated: Some synthetic proofs encode the collinear intersections through directed ratios.

• Desargues's theoremCompared with: It gives a metric-ratio route to related triangle incidence results, unlike Desargues's purely projective statement.

• Monge's theoremRelated: Its directed-ratio relation proves collinearity of the three centers.

• Incenter–excenter lemmaRelated: It can test collinearity in configurations involving centers and sidelines.

• Seven circles theoremRelated: It can certify the final line once the relevant intersection ratios are known.

• Thomsen's theoremCompared with: It concerns a single transversal and a ratio condition rather than iterated perspectivities.
