WebThis theorem, that when two straight lines cut one another the vertical and opposite angles are equal, was first discovered, as Eudemus says, by Thales, though the scientific demonstration was improved by the writer of the Elements. Equality of triangles (by two angles and a side). In geometry, Thales's theorem states that if A, B, and C are distinct points on a circle where the line AC is a diameter, the angle ∠ ABC is a right angle. Thales's theorem is a special case of the inscribed angle theorem and is mentioned and proved as part of the 31st proposition in the third book of Euclid's Elements.

WebThere are many ways to prove this theorem. One of the most classic proofs is as follows: We know AO=BO=CO AO = BO = C O as all of them are the radii of the circle. Hence, \angle OAB=\angle OBA ∠OAB = ∠OBA and …
WebApplying a theorem known to Thales, the side-angle-side (SAS) theorem—two triangles are congruent if two sides and the included angle are equal—yields two sets of congruent triangles: AOD ≅ BOC and DOB ≅ COA. Since the triangles are congruent, their corresponding parts are equal: ∠ ADO = ∠ BCO, ∠ DAO = ∠ CBO, ∠ BDO = ∠ ACO, and so … kindle fire hdx 7 softwareWebT H A L E S Thales Theorem: An angle inscribed in a semicircle is right. It is to be shown that if the triangle ABC is inscribed in a circle with the side BC being a diameter of the circle, then the angle BAC is a right angle.
