1. DEF is the medial triangle of ABC and XYZ s the medial triangle of DEF. If the perimeter of XYZ is 5 what is the perimeter of ABC? (no picture)

2. In triangle ABC, the acute angles are angle B=60 and angle C=30. The centroid of triangle ABC is G If AB=1, what is AG? (no picture)

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!

 

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

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

\(P_{ABC}=20\)
