Răspuns :
Fie A, B,C, masurile unghiurilor triunghiului
Atunci
2A=3B=6C
A=3C
B=2C
A+B+C=180°
3C+2C+C=180°
6C=180°
C=30°
A=3C=90°, triunghi DREPTUNGHIC
Atunci
2A=3B=6C
A=3C
B=2C
A+B+C=180°
3C+2C+C=180°
6C=180°
C=30°
A=3C=90°, triunghi DREPTUNGHIC
2A=3B=6C⇒B=2C si A=3C
A+B+C=180°
-------------------
3C+2C+C=180°
6C=180°
C=30°
B=2C=60°
A=(3C=)90°
A+B+C=180°
-------------------
3C+2C+C=180°
6C=180°
C=30°
B=2C=60°
A=(3C=)90°
