Sir pl. most essentially reply to my scrap wenever u hav time... i'll wait.....
Coz u r the one who has gone thru this grill n hav cum out trumps!!!!
The second part is very simple
The height is H
the angle is A
then The distance of the foot of the pole from each vertex is given by
H cot A for all the 3 vertices
which is equal.
SO it gives you the circumcenter :)
hmmm.... yah..... y didnt it strike me then!!!!
k neways now i got it.... hope i'll not 4get these things on the D'DAY
