Exercice 2 : Retrouver les longueurs et formes des triangles dans un rectangle/carré/losange

\(TUVW\) est un losange dont les diagonales se coupent en \(O\).
On sait que \(14 m = TV\).

Donner la longueur de \(UW\) si l'énoncé le permet. Dans le cas contraire, écrire "Impossible".

Donner la longueur de \(WO\) si l'énoncé le permet. Dans le cas contraire, écrire "Impossible".

Quelle est la nature du triangle \(UOV\) ?
(On choisira la réponse la plus précise possible)
