How calculate angle between 3 pts?

Postby Steve Adams » Tue Oct 11, 2005 2:42 pm

I know I could inverse between them and calc from the bearings, but how do I get FG to tell me what the angle is?
Thanks,
Steve

go to Calculations---Inverse----You see 4 choices on the Bottom...Radial Inv.--Line---Rad---3PT highlight the RAD Then enter the 3 points into the boxes.....Example: angle 1-2-3
1 goes in 1ST
2 goes in ARC
3 goes in 2ND
Hit enter after you enter each point number

Then you see two lines on top of the screen..mine shows PC point :2 and Curve Direction :Right Tap on that box to open the full calcualtion list and the Delta reading is the angle
