Corners are at RA (right arm), LA (left arm), LL (left leg).
Number of L's at a corner tell how many + signs are at that corner [eg LL is ++].
Sum of number of L's of any 2 corners tells the name of the lead [eg LL-LA is lead III].
For reference axes, the negative angle hemisphere is on the half of the triangle drawing that has all the negative signs; positive angle hemisphere contains only positive signs.
