| Line |
The specified angle of two
intersecting lines is always the smaller of the two possible angles
a and b. Hence:
a + b = 180°.
The angular relationship of non-intersecting lines is
specified by the angle between the two direction vectors of the lines. |
The angle is the angle between the normal
vector of the plane and the line. It is measured at the piercing point
of the line through the plane. |
The angle is the angle between the cylinder axis and the line. The specified
angle is always the smaller of the two possible angles a
and b. Hence: a +
b = 180°.
If the cylinder axis and the line do not intersect, the
angle between the two direction vectors is specified. |
