Am si eu o nelamurire nu prea stiu sa rezolv o problema la Geometrie ca nu a mai avut timp profa sa ne explice:
Desenul l-am facut cu Paint l-am uploadat la http://www.99poze.ro/Desen_Geometrie/1/ .
Cerintele sunt.


Se da figura 6(Cea Uploadata).Se stie ca <1 Congruent <5:
Demonstrati:

a) <4=<8 ; <3=<7 ; <2=<6
b) <3=<5 ; <4=<6
c) <1=<6 ; <2=<8
d)m(<3)+m(<6)=180* ; m(<4)+m(<5)=180*
e) m(<2)+m(<7)=180* ; m(<1)+m(<8)=180*

Noua ne-a predat doar care sunt unchiurile alterne interne,alterne externe,etc.
Daca ne dadea macar un model de astfel de exercitiu era alt ceva.Maine cred ca o sa ne explice.
Ca ora trecuta nu mai era nici timp.
