TRIANGULATE

The point a distance from each of two points: where two circles round them cross.

Syntax

TRIANGULATE(A,B,dA,dB,side)

Argument	Meaning
A, B	The two points.
dA, dB	How far the new point is from A and from B.
side	Which of the two crossings: positive (or 0) for the one on the left of the way from A to B, negative for the one on the right.

Result

A position.

Examples

In the example drawing:

Expression	Gives
`TRIANGULATE(P0,P1,300,400,1)`	`[180,240]`
`TRIANGULATE(P0,P1,300,400,-1)`	`[180,-240]`

Notes

The Two Distances snap mode makes its points this way. It is an error if the two points are the same, if a distance is negative, or if the circles don't meet (the distances are too short to reach, or one circle is inside the other); circles that just touch give the point where they touch.
