Goemetry riddles.. Only remember 4 angle in a polygon always equal to 360 degree. Opposite angle when two line intercept. The rest all go back to math teacher liao ;)
dammm…! Reading the .pdf brings me back to my nightmarish high school years! I swore to myself I’ll never calculate anything to do with trigo anymore after I left high school.
whoa… trigonometry… long time never see
erm… the total of 4 angles in a square is 360? etc etc… hehehe

Goemetry riddles.. Only remember 4 angle in a polygon always equal to 360 degree. Opposite angle when two line intercept. The rest all go back to math teacher liao ;)
I have also returned my knowledge to the teacher…
By looking at it, it can’t be solved I guess. My best guess is that
angle p = angle r
length of = length of b
as for angle q = no idea.
eh since when you teach this or you bekamming tution teacher ar ?
your student ask you dunno then you ask blogger ar? my math kantoi la sorry la
jasonlioh : Divide it into triangles.
pisang : It’s for remote control helicopter.
i also gave back to school liao.
but i’m sure angle p does not equal to angle r. that’s because b, e & c are not parallel.
my reckoning, angle p equals to q (though not necessarily right angle), to satisfy the length conditions in the first diagram.
therefore, aa and dd is parallel, which makes e equals to b (and they’re not parallel).
as for the r angle, use law of sine/cosine or pythagorean theorem, which i totally forgotten how to… heeeheeheheh
(there, my pathetic attempt to solve problems.)
yeah i vaguely recall have to chop it into 90 degree triangles…
The work will be more easier when it involves real values. How ever I gave it a try, any experts to help me simplify it?…
Hmm… Wher should I upload it?…

Wah lao! Tabek tabek at guardog! Thank you!
Yeah, using those sine and cosine rules.
I was half way doing it using Excel.
Omgoodness! Guardog! Whoa! *tabek as well*
(psst, u single? Lol. jk. =P)
*pass 不求人 to anastasia*
whoa…. *kow tow to guardog*
terror-nya
dammm…! Reading the .pdf brings me back to my nightmarish high school years! I swore to myself I’ll never calculate anything to do with trigo anymore after I left high school.
p and q is the same, whereas r is (180-p)
e would be b rite?
answer me pelease, cos i registered just to comment on this crap
nice knowing u
LOLOL @ y4ng. You should spend more time reading the comment. Please kowtow to guardog.
doc: pass “Does not help others for help” to anastasia? That’s what babelfish told me. Lol.
anastastia : The fish is right. It’s a stick for inducing self pleasure.
Doc: Lol, not that desperate thankyouverymuch…
