Two Applications of the Generalized Ptolemy Theorem
Web1. This problem is some applications of Ptolemy's theorem from Euclidean geometry: Suppose ABCD is a cyclic quadrilateral.

WebPtolemy Theorem can be used to prove two results in plane geometry. The first result, Theorem 1, is a generalization of a theorem that was originally pro- posed in 1938, as a MONTHLY problem, by the French geometer Victor ThCbault [15]. ThCbault's Theorem remained an open problem (allegedly a tough one, see [lo, p. 70- WebSep 21, 2024 · 3 Answers Sorted by: 1 Here's a scheme of the solution. By the cosine rule you can find angles ∠ABC and ∠ACB : cos(∠ABC) = 4 5, sin(∠ABC) = 3 5, cos(∠ACB) = 154 170, sin(∠ACB) = 72 170. From that you get CD = BD ′ = 30. Let F ′ be the point where line ED ′ meets the tangent at B, and apply the sine rule to triangle BD ′ F ′. WebWe can prove the Pythagorean theorem using Ptolemy's theorem: Prove that in any right-angled triangle \triangle ABC ABC where \angle A = 90^\circ, ∠A = 90∘, AB^2 + AC^2 = BC^2. AB2 +AC 2 = BC 2. Let ABDC ABDC be a random rectangle inscribed in a circle. Applying … keyfort group meet the team
