A line segment that has been cut exactly in half
A bisector cuts a line SEGMENT into two congruent line segments. A line has indefinite or infinite length.
If you cut a rectangle in half you wouldn't get a solid figure at all, since a rectangle is a plane figure. If you made a straight line cut you would get either a triangle or a quadrilateral of some variety depending on exactly how the cut was made.
It is called a frustum.
I believe that is called a chord. Yes, a chord is the straight line segment that crosses a circle, from one side of the circle to the other. The biggest possible chord is the diameter. The curved part of the circle, cut off by the chord [or chords], is the arc or the angle.

A line segment that has been cut exactly in half
To bisect anything is to cut it in half. So if one line segment bisects another line segment, then the second segment is divided into two equal lengths.
A plane figure.

Cut a straight line segment. At its end, rotate the paper in the scissors and make another straight cut. From the end of the second line, again rotate the paper and keeping ways from the earlier cuts, make yet another straight cut. Repeat for the fourth and fifth cuts. Then, rotate and cut, but this time finishing somewhere on the first line segment. You will have cut a shape with six straight sides: a hexagon.
A shape that when you draw a line on the shape and cut along the line you get two identical shapes. A circle is an example.

Something like a pencil or log, because it was cut off from something bigger.
