geometry[FindAngle] - find the angle between two lines or two circles

Calling Sequence

FindAngle(u, v)

Parameters

u, v

-

two lines or circles

Description

• 

The routine finds the angle between two lines u and v, or between two circles u and v.

• 

When u and v are two lines, the smaller angle between two lines is reported.

• 

When u and v are two circles, the angle returned is in the range 0..Pi.

• 

The command with(geometry,FindAngle) allows the use of the abbreviated form of this command.
