| It then follows from the Menelaus theorem, that every three such points are collinear provided all or two of the bisectors are external. |
|
| Perpendicular bisectors of two pieces of its medians form a hexagon with opposite sides parallel. |
|
| The common perpendicular bisectors of parallel sides bisect the angles of the triangle formed by the extensions of the three equal diagonals. |
|
| Indeed, let L P, L Q and L R be the points of intersection of bisectors of angles CPB, AQC, and BRA with sides CB, AC and BA, respectively. |
|
| The right-hand example shows the menu displayed when you point the cursor at the point of intersection between the three bisectors of a triangle. |
|
| Located where the bisectors of a triangle's three angles intersect, the incenter is the center of the largest circle that can be inscribed inside that triangle. |
|
| But even then an elementary framework will not attain the broad outlook of Morley's theory that includes the angle bisectors and trisectors under a single roof. |
|
| All area bisectors of a circle or other ellipse go through the center, and any chords through the center bisect the area. |
|
| Perpendicular bisectors of these two lines were drawn and the intersection point was the centre of the femoral head. |
|
| Finally we construct the three perpendicular bisectors of the sides of the triangle: lines perpendicular to each side, through the midpoint of the side. |
|
| When it is perceived as a square one perceives a symmetry about the bisectors of the sides, and when it is perceived as a diamond one perceives a symmetry about the bisectors of its angles. |
|
| These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. |
