Finding the Points of Tangency
Keep in mind that the ultimate goal is to have GeoCalc determine the points of tangency
between the lines and the arc. Since the
FIND ARC
function calculates the arcs which are
tangent to the two selected lines, the ends of the arcs are the points we need. We just
have to select the arc and have GeoCalc find the end points.

The three resulting points are the center and the ends of the arc. The end points are the
ones we are after; they are points C and D in our drawing.
