need some help with Geometric demostrations
I've found these two interesting problems in an old book
from the "MIR" editorial(RUSSIA).
Any kind of suggestions to get to a convincing conclusion
wil be appreciated.
Note: the top part are meant to be premises.
I have no choice but to use megaupload to upload the jpg since
I couldn't use the "insert image" option, I dont know why but always reject me
the warning "this is not a valid image file".
