Thales's theorem

WebIn 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. [1] WebTwo Algebraic Proofs using 4 Sets of Triangles. The theorem can be proved algebraically using four copies of a right triangle with sides a a, b, b, and c c arranged inside a square with side c, c, as in the top half of the diagram. The triangles are similar with area {\frac {1} {2}ab} 21ab, while the small square has side b - a b−a and area ...
