ang(apex,p1,p2,p) Determines the angle between lines (apex,p1) and (apex,p2).

The lines are considered 3D. The last parameter, point p, is used to define the

orientation of the angle. The angle is measured counterclockwise with respect

to the axis going from apex to p.

The following examples show how angles are measured.

You can determine the angle between the two sides of a triangle using the

ang function, as shown in the following example:

Command: cal

>> Expression: ang(end,end,end)

Select the apex of the angle, and then select the two opposite vertices.
