| 1. | Only two of the three bisectors are needed to find the centre.
|
| 2. | The intersections of these angle bisectors give the centers of solution circles.
|
| 3. | Cayley-Klein Voronoi diagrams are affine diagrams with linear hyperplane bisectors.
|
| 4. | The circumcenter of a triangle can be perpendicular bisectors.
|
| 5. | The perpendicular bisectors of the sides also play a prominent role in triangle geometry.
|
| 6. | The cleavers are parallel to the angle bisectors.
|
| 7. | Hence, the center is the point of intersection of any two perpendicular bisectors.
|
| 8. | The intersection P of these two bisectors is the pole of the planar displacement.
|
| 9. | The perpendicular bisectors of any two sides of a triangle intersect in exactly one point.
|
| 10. | In a triangle, four basic types of sets of concurrent lines are perpendicular bisectors:
