Ok

I need to find out how to map an equilateral triangle inside a circle that is centered in a square.

The size of the square is all the real reference I have

Id like to have the triangle point down inside the circle

Uhghhh hard to ezplain

Mainly because I dont really NEED the triangle, I just need 3 points on the circle 120 degrees apart with one being at 180*

WAHGHGHH MY HEAD

See if this will do it (I think this is what you're talking about):

Draw your square and make the circle touch all 4 sides...I think that's easy enough.
Now, make crosshairs in your square/circle...this will be the center.
Where the vertical crosshair hits the bottom line of the square, put a dot there. Then, take your protractor (angle measuring dohickey) and center it at the center point of your crosshairs. Now, put dots 120 degrees (from your dot on the bottom line) on the outside of the circle. Now you have 3 dots...connect 'em and you're done.

Wow, I have no idea if I explained that in a coherent manner...let me know if you understand.

What is the size of the square??? Do you have a compass (not the kind that shows which direction you are going)... If so, find the center by connecting the diagonals (like in the above description)Then set your compass so that it draws a circle that touches the box on each side. Without changing your compass setting, put it where the circle touches the bottom edge(this will be your bottom vertex), then mark the circle, move to that mark and make another mark on the circle....continue this until you get back to your starting point. You should make 6 marks(counting your starting point), just connect every other mark and you have an equilateral triangle. /forums/images/graemlins/thumb.gif
