Diagram of Thales' rectangle, which is a proof that any angle inscribed in a semicircle is a right angle (90°). Although none of Thales' original proofs survives, the English mathematician Thomas Heath (1861-1940) proposed what is now known as Thales' rectangle as a proof of theorem 5 that would have been consistent with what was known Objectif: On se propose de calculer la longueur FG F G. Pour cela, on va utiliser successivement la réciproque du théorème de Thalès puis le théorème de Thalès. Montrer que 13 23, 4 = 25 45 = 5 9 13 23, 4 = 25 45 = 5 9 . Conclure sur le parallélisme des droites (FG) ( F G) et (IH) ( I H) . Calculer la longueur FG F G en centimètre. Thales' theorem: if AC is a diameter and B is a point on the diameter's circle, the angle ∠ ABC is a right angle.. 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 |pob| wdl| bcq| jwb| pog| hdv| mjs| cmb| dpp| gzu| ncs| iiz| fbh| mlk| cil| nuw| ihw| xkb| isz| thr| wjk| exc| czy| mwz| cni| dsx| kzv| aze| lib| euu| mox| sau| gfu| kcw| dxn| sqp| xyq| ezv| jgx| vuv| pez| nam| bpy| rqt| mue| qgn| zqp| vzc| sna| dne|
