Every line segment has exactly one bisection point - not "at least one".A line segment has a length that is a finite real number, x, of some measurement units. Every real number can be divided by 2 to give another real number, y. Therefore y = x/2 or x = 2y.A point that is y units from one end of the line will also be x - y = 2y - y = y units from the other end. That is the point is the bisection point.
A bisection is a division or the process of division into two parts, especially two equal parts.
*Note that it is assumed you know what the terms diameter, perpendicular, bisect/bisection and intersection mean in relation to geometry. If not, they are explained in the discussion area. To construct a regular pentagon using a compass and ruler (a longer, but more precise method): # Draw a circle in which to inscribe the pentagon and mark the center point O. # Choose a point A on the circle; this will be one vertex of the pentagon. Draw the diameter line through O and A. # Construct a line perpendicular to the line OA passing through O. Mark its intersection with one side of the circle as the point B. # Construct the point C as the midpoint of O and B. # Draw a circle centered at C through the point A. Mark its intersection with the line OB(inside the original circle) as the point D. # Draw a circle centered at A through the point D. Mark its intersections with the original circle as the points E and F. # Draw a circle centered at E through the point A. Mark its other intersection with the original circle as the point G. # Draw a circle centered at F through the point A. Mark its other intersection with the original circle as the point H. # Construct the regular pentagon AEGHF. To construct a regular pentagon using a protractor (less time, but not as accurate): # Make a short line. This will be one side of the pentagon. Label the ends A and B # Place the baseline of the protractor on this line, with the centre at A. # Mark the point of 108o with a dot. # Make another line which starts at A, is the same length as AB and goes towards the dot. # Repeat the use of the protractor on the newest line you have drawn three more times. The final line should meet up with B.
Easiest is to use a protractor. Alternative: Draw a 90 degree angle. Bisect the external angle so that it is 45 degrees. Trisect that angle so that the angle adjacent to the 90 degree angle is 15 deg Then 90 + 15 degrees = 105 degrees. Both, bisection and trisection require the use of a compass (and ruler).

The line of bisection of an ellipse is called the tangent.

An improved root finding scheme is to combine the bisection and Newton-Raphson methods. The bisection method guarantees a root (or singularity) and is used to limit the changes in position estimated by the Newton-Raphson method when the linear assumption is poor. However, Newton-Raphson steps are taken in the nearly linear regime to speed convergence. In other words, if we know that we have a root bracketed between our two bounding points, we first consider the Newton-Raphson step. If that would predict a next point that is outside of our bracketed range, then we do a bisection step instead by choosing the midpoint of the range to be the next point. We then evaluate the function at the next point and, depending on the sign of that evaluation, replace one of the bounding points with the new point. This keeps the root bracketed, while allowing us to benefit from the speed of Newton-Raphson.
Bisection.
It is dividing an angle into two equal parts.
In geometry a bisection refers to a division into two equal parts, for instance a bisection of an angle will involve constructing a line which divides the angle into two angles of equal size. A bisection of an angle on the plane ( i.e. a angle drawn on a 2 dimensional surface) can be performed using only a straight edge and a pair of compass.
In the absence of other information, it is the most efficient.
In geometry a bisection refers to a division into two equal parts, for instance a bisection of an angle will involve constructing a line.
1. it is always convergent. 2. it is easy
A rectangle has two lines of symmetry (the bisection of the length and width).
