From that point you draw a line at 90* to the radius/diameter, crossing both edges of the circle, and those two points are 120* apart.<br /><br />It's harder to describe than watching him do it.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.comtag:blogger.com,1999:blog-4901205574058136834.post-64727874039312548682012-10-07T19:03:06.162-07:002012-10-07T19:03:06.162-07:001/4 of the diameter will give you 120 degrees, I d...1/4 of the diameter will give you 120 degrees, I don't remember the math for the rest of it though... :-(Old NFOhttps://www.blogger.com/profile/16404197287935017147noreply@blogger.comtag:blogger.com,1999:blog-4901205574058136834.post-76028913544592196332012-10-07T18:16:55.422-07:002012-10-07T18:16:55.422-07:00Okay, so how does one place the point on the diame...Okay, so how does one place the point on the diameter line?
