| The use of collinear beam geometry facilitates the alignment of the overlap of the two foci and ensures high image quality. |
| If all points are collinear, it has zero area and is represented by a segment. |
| The segments that make the angle must belong to the same face and not be collinear. |
| Exact alignment occurs when these three points are collinear in the frontal plane. |
| In the first of these evaluations of angle perception, subjects were asked to rotate a test line until it appeared collinear with the indicated arm of the inducing angle. |
| As given earlier, the three relevant intersection points for six points on the circle will be collinear. |
