∙ 6y agoIn general, they are not. In an isosceles triangle, the perpendicular bisector of the base is the same as the bisector of the angle opposite the base. But the other two perp bisectors are not the same as the angle bisectors. Only in an equilateral triangle is each perp bisector the same as the angle bisector of the angle opposite.
A diagonal always forms an angle bisector in a square. In a rectangle, trapezoid, or any other quadrilateral, a diagonal does not always bisect the angles.
There is no general reason. But before I can answer in more detail, what were you bisecting? A line, an angle, a polygon, some other shape?
A perpendicular segment refers to a line that cuts another at right angle (90 deg). A perpendicular bisector refers to a line that cuts another at right angle while splitting the two sides equally. In short, it is just a 90 degree line in the midpoint (exact centre) of the other line
It depends on what is given.In general, one half of the bisected angle is proven to congruent to the other half. By the Definition of an Angle Bisector, the bisected angle can be proven bisected.---- To show that two angles are congruent:One way to prove the two angles congruent is to show that their measures are equal. This can be done if there are numbers on the diagram. Use the Protractor Postulate or the Angle Addition Postulate to find the smaller angles' measures, if they are not directly marked. Then use the Definition of Congruent Angles to prove them congruent.Given that the smaller angles correspond on a congruent or similar pair of figures in that plane and form an angle bisector, the Corresponding Parts of Congruent Figures Postulate or Corresponding Parts of Simlar Figures Postulate may be used.

No. A bisector divides and angle in two and an angle can be divided into two only once. After that you are dividing other angles.
The method is exactly the same as for bisecting any other angle. You may find it easier to bisect the "other side" of the reflex angle, which will be at most obtuse and then extent the bisector through the vertex to the other side.The method is exactly the same as for bisecting any other angle.

A bisector is a line or curve which bisects or divides a line segment, angle or other figure into two equal parts.
A perpendicular bisector is a line which cuts a line segment into two equal parts at 90°.

Yes - the altitude of an equilateral triangle is perpendicular to the side chosen as the base and bisects that side and the opposite angle. Also, the altitude of an isosceles triangle when measured from the third side (the side that is not equal to the other two sides) is a perpendicular bisector of the base and also bisects the opposite angle.

There are at least two ways to find 1/4 of an angle. One is to measure the angle with a protractor and divide by 4. The other is to use Euclid's straight-edge-and-compass construction for the bisector of the angle. This gives half the angle. Then use the same construction again on the half angle to get one fourth of the original angle.
It is approx 1087.6 N along the bisector of the two lines of action.
