a + b + c = 250
b+c +75 = a + b ==> a = c+75
c = b - 25 ==> b = c + 25
a /-------/+75
b /-------/+25
c /-------/
250 - (25+75) = 250 - 100= 150
150 : 3 = 50 (valoare unui segment egal)
a = 50+75 = 125
b = 50 + 25 = 75
c = 50
Verificam:
125 + 75 + 50 = 250
75+50 = 125 (b+c)
125 + 75 = 200 (a+b)
200 - 125 = 75
