26.15.13 Checking whether two circles in the plane are orthogonal
See Section 27.11.5 for checking for orthogonality in
3D geometry.
The is_orthogonal
command determines whether or not two lines or circles are orthogonal.
-
is_orthogonal takes two arguments:
C1,C2, two objects, both lines or both circles.
- is_orthogonal(C1,C2) returns 1 if
C1 and C2 are orthogonal and returns 0 otherwise.
Examples
| is_orthogonal(line(0,1+i),line(i,1)) |
| is_orthogonal(line(2,i),line(0,1+i)) |
| is_orthogonal(circle(0,1+i),circle(2,1+i)) |
| is_orthogonal(circle(0,1),circle(2,1)) |
