How do I create a tangent line through a point in XyzPilot?

Use Line/P,Tanto,C to create a line through a point tangent to a circle. Two tangent lines exist — use a direction selector.

Full Answer

Use the Line/P,Tanto,C operator. Two tangent lines exist from any external point to a circle — the direction selector specifies which one. The point must be outside the circle.

XyzPilot Example

C0 = Centre (0,0), radius 20 P0 = (50, 0) [external point] Line/P0, YLarge, Tanto, C0 → L0: upper tangent line Line/P0, YSmall, Tanto, C0 → L1: lower tangent line
