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 ...

WebTheorem about 2 lines intercepted by a pair of parallels (see en:Intercept theorem) This theorem is called Thales' theorem as well (in other languages: Théorème de Thalès, Teorema di Talete, Teorema de Tales, Twierdzenie Talesa, Strahlensatz).The Category:Thales' theorem however is for another theorem named after Thales (en:Thales' … WebThales’ theorem is considered as a special case of the inscribed angles theorem. This theorem tells us that, if we have a triangle inscribed in a circle as shown in the following diagram, the angle formed at vertex B is always a right angle. WebPythagoras Theorem A well known and significant theorem in mathematics is known as the Pythagoras Theorem which is attributed to a Greek who existed about the same period as Thales. The theorem of Pythagoras is said to be the most important geometrical discovery of the ancient Greek world. ron willoughby sniper
