hello trig masters: i have a simple question: say i have to points A and B (0 and 1 in the comp). i want to find a third point in a perpendicular bisector (GREEN line in the comp) of AB within a certain distance of the middle point of AB. i made it in the following composition with some help of the forums but i cant make the distance part to work. i allways have to make the X coordinate of the third point. can you guys help i've been searching for circle intersecting the bisector but got lost....

please thank you all great masters of the trig world :)

bernardo ps: got to work on my english.

Re: a trig question

for trig. questions, I recommend having a look at Paul Bourke website: http://local.wasp.uwa.edu.au/~pbourke/geometry/

and the two circles problem : http://local.wasp.uwa.edu.au/~pbourke/geometry/2circle/

He's a goldmine of information.
