AM-mediana ⇒AM=BC/2 ⇒BC=2AM=2*8=16
AM=BM=CM= BC/2
ΔABC-echilateral, AB=BC=AC=16 ⇒h=l√3/2=16√3/2=8√3
AM=BM=CM= BC/2
ΔABC-echilateral, AB=BC=AC=16 ⇒h=l√3/2=16√3/2=8√3
ΔABC,
AB = BC = CA = l
MA = MB = MC = r = 8cm
---------------------------------
latura l = ?
inaltimea h = ?
---------------------------------
AOB = BOC = COA = 60°
l = 2rsin60° = 2 * 8 * 0.866 = 13.856
h = lsin60°= 2rsin²60° = 2 * 8 * 0.75 = 12
