Line Tangent to Circle
Curve Tangent to Circle.
Will compute the location of a line that is tangent to the specified
sides of two specified circles.
Tangent Line: determines which sides of the
circles the computed line will be tangent to as
you occupy the 1st Radius Point and face the
2nd Radius Point. (See illustration below.)
1st / 2nd Radius Pt: defines the points around
which the circles are computed.
Radius: defines the radius of the circles that
are used to compute the Tangent Line.
; Store Tan Pt: When checked, will store the
computed tangent points.
Solve : computes the location of the tangent
line and optionally stores the two tangent points.
Results
TP 1: displays the coordinates for the first
tangent point.
TP 2: displays the coordinates for the second
tangent point.
Azimuth: is the azimuth of the tangent line from
the first tangent point to the second.
Distance: is the length of the tangent line.
