Question

Vreau si eu sa imi rezolvati problema aceasta urgentttttttttttttttttttttttttttttt

in triunghiul echilateral abc construim bisectoarea bd ,d e parantea AC si paralela prin punctul d la dreapta AB care intersecteaza latura BC in punctul e daca BD INTERSECTAT CU AE EGAL F aflati  masurile unghiurilor triunghilor
a triunghi bde
b triunghi afd urgenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt

Answer 1

B bisectoare.rezulta ca unghi(DBE)=30.Avem tr DEC unde DC=CE.dar ar DE e jumatate din AB si DC si CE sunt jumatatile lui AC si BC.Resulta ca tr DEC echilateral.mas unghiurilor lui 60 grade.
u(ADB)+U(BDE)+U(EDC)=180
90+BDE+60=180
BDE=180-150=30
BED=180-DEC=180-60=120.Si am aflat tt unghiurile triunghiului BED
Trecem la AFD
Intr un triunghi echilateral bisect e si inaltime.U(ADB)=90.
DFE=180-FDE-FED=180-30-30=120
AFD=180-DFE=180-120=60
FAD=180-ADF-AFD=180-90-60=30
AM AFLAT ASADAR SI MASurile TR AFD
FAD=30 AFD=60 ADF=90
