[Ipe-discuss] Drawing a circle onto an existing tangent

ahoj ondro,

with ipe 6 you could proceed as follows:

1. select the line (segment), then the first point, click on Ipelets ->
Goodies -> Make parabolas.

2. select the line (segment), then the second point, click on Ipelets ->
Goodies -> Make parabolas.

if your line segment is long enough, the two parabolic arcs intersect.
the (only) intersection point is the center of the circle that goes
through the two points and is tangent to the line.

enjoy! :)
