can u post up the solution? plzthey are too easy.
ty!!!!This is my proof for part i of 2.
OV = OW (equal radii)
PV = PW (tangents drawn from an external point equal)
OP is common
therefore triangle OPW congruent to triangle OPV (SSS)
therefore angle WOM = angle MOV (corresponding angles congruent triangles equal)
OV = OW
OM is common
therefore triangle MOV congruent to triangle MOW (SAS)
therefore MW = MV (corresponding sides congruent triangles equal)
therefore OM perpendicular to VW (line through centre which bisects a chord is perpendicular to it)
yeh lol, u cant rep ppl till you get rep power urself.ty!!!!
(I tried to rep u, but its not letting me)
dw about the rest of them. part ii onwards seem stupid.
In what sense?part ii onwards seem stupid.
tyRepped him for you.
those theorems u linked to arent part of the hsc syllabus...In what sense?
The vast majority of HSC geometry problems are either special cases or direct proofs of theorems not in the syllabus; compare last year's q7 from the 4u paper with http://en.wikipedia.org/wiki/Ptolemy's_theorem. Clearly the question is no more or less stupid as a result.those theorems u linked to arent part of the hsc syllabus...
