Circle tangential to two lines (2D)

You can add an arc or circle between two lines so that the lines are tangent to the arc/circle. The radius will define the position of an arc or circle towards the tangent lines. The arc will be drawn counterclockwise between the selected lines.

1. Select the first line, which is the tangent of the arc/circle to be added.
2. Select the second line.
3. Enter the radius.

A third point must be selected for a circle that is the tangent of two other circles.
