Question

ip = DEFG paralelogram
GE intersectat DF={0}
|GO| =3 cm
|DO| = 5 cm
|OE| =?
|DO|=?
|GE|=?
|DF|=?​

Answer 1

Explicație pas cu pas:

Daca |OG|=3 cm => OG= |3|= 3 cm

Daca |OD|=5 cm => OD=|5|= 5 cm

DEFG-paralelogram

GE intersectat DF={O } => O-mij GE si O-mij DF

O-mij GE => OG=OE= 1/2GE=> GE= 6 cm

O-mij DF => OD=OF= 1/2DF=> DF= 10 cm

Inseamna ca |OD|=|OF|=5 cm

|OG|=|OE|= 3 cm

|DF|= 10 cm si |GE|= 6 cm
