Gennemgang af opgave: Vinkler i trekanter (skærende linjer)

Lær at finde størrelsen på vinkler i trekanter og skærende linjer. Vi bruger begreber som supplementære vinkler (vinkler der sammen er 180 grader), topvinkler (modsatte vinkler, når to linjer skærer hinanden) og udvendige vinkler (vinkler udenpå en trekant). Lavet af Sal Khan.
