Modul 7: Vinkler mellem skærende linjer

# Manglende vinkler med en transversal

Når en tredje linje, kaldet en transversal, krydser to parallelle linjer, vi kan bestemme størrelsen af flere vinkler, hvis blot et vinkelmål er angivet. Dette gøres ved at bruge forskellige matematiske sætninger. Dem vi skal se på her omhandler ensliggende vinkler ved parallelle linjer, topvinkler og supplementære vinkler. Lavet af Sal Khan.

• Kan man sige at topvinkler er spejlet i den parallelle linje?
