1. DEF ist das mediale Dreieck von ABC und XYZ ist das mediale Dreieck von DEF. Wenn der Umfang von XYZ 5 ist, was ist der Umfang von ABC? (kein Bild)

**Hello Guest!**

\(P_{ABC}=2\times P_{DEF}\\ P_{DEF}=2\times P_{XYZ}\\ \color{BrickRed}P_{XYZ}=5 \)

\(P_{ABC}=5\times 2\times 2\)

\(P_{ABC}=20\)
