Mittelparallele
Serie 04 / Schwierigkeitsgrad 1
Aufgabe 1
Konstruiere bei der folgenden Figur die Mittelparallele. Achte darauf sorgfältig zu zeichnen!
Aufgabe 2
Statt mit der gängigen Formel kann man den Flächeninhalt eines Trapezes auch mithilfe der Mittelparallele berechnen. Die Formel lautet dann: A=m ×h
Schreibe die Rechnung auf die nächste Seite.
Wie lautet die gängige Formel, um die Fläche von Trapezen zu berechnen?
Formel: ____________________________________________________________________________
Wie groß ist die Fläche eines Trapezes mit den Maßen h = 8 cm und m = 12 cm?
Antwort: __________________________________________________________________________
Aufgabe 3
Familie Sänger möchte einen großen trapezförmigen Pool in den Garten bauen lassen. Dabei ist ihnen wichtig, dass der Pool 6 m „hoch“ ist und insgesamt eine Fläche von 72 m² bedeckt.
Schreibe die Rechnung auf die nächste Seite.
Wie lang muss die Mittelparallele des Pools sein?
Wie lang müsste sie sein, wenn der Pool doch lieber 8 m „hoch“ sein soll?
Antwort: ___________________________________________________________________________
