Winkelsumme im Viereck und Verallgemeinerung (Klasse 7)

0:17 Sum of Interior Angles in a Quadrilateral 4:01 Generalization Using a Pentagon and Hexagon 8:18 Summary At the beginning of the video, building on the knowledge of the sum of interior angles in a triangle, the sum of the interior angles of any quadrilateral is calculated. The general formula for calculating the sum of interior angles in any n-gon is then derived inductively using the examples of a pentagon and a hexagon.
