| 11. | Collinear arrays of dipoles are high gain omnidirectional antennas.
|
| 12. | Portable radios usually use collinear arrays of vertical dipoles.
|
| 13. | In Euclidean geometry, any three non-collinear points determine a plane.
|
| 14. | Nearly collinear points often lead to numerical instability in computation of the circumcircle.
|
| 15. | Three non-collinear points in space suffice to determine the orbital plane.
|
| 16. | Two variables are perfectly collinear if there is an exact linear relationship between them.
|
| 17. | A complete quadrangle consists of four points, no three of which are collinear.
|
| 18. | Four distinct points can either be collinear, coplanar or determine the entire space.
|
| 19. | Then A0, B0, C0 are collinear.
|
| 20. | Only sound with parallel collinear phase velocity vectors interfere to produce this nonlinear effect.
