four points to construct intersection point and angle
5) four points to construct intersection point and angle
Purpose: to measure four points from two lines to construct
the intersection point and the intersection angle
of the two lines.
Example: the point A and B in the line 1 ;
the point C and D in the line 2 ;
to construct the intersection point and
the intersection angle of the line 1 & 2
Different coordinate point selecting order will result in varied angle in response.
