Compare the distance to a known length.
Measure.
If you know the coordinates of the two dots in an orthogonal coordinate system, use Pythagoras' theorem to find the distance.
Say point 1 has coordinate (Ax,By) and point 2 has coordinate (Cx,Dy) then the distance between 1 and 2 is the square root of ((C-A)2 + (D-B)2))

Take a compass, extend it about 3/4 of the length of the segment. Then from one end of the segment, draw a 180 degree arc. From the other end draw another arc. Connect the points where the arcs intersect. Where the line intersects with the segment is the midpoint of the segment. That is how you bisect a segment to find the midpoint - geometrically.
|32 - 132| = |-100| = 100 |32 - 132| = |-100| = 100

i dont know
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
double the length
It depends on what information you do have.
if the segment is the whole length of the circle divide it by 2
One characteristic of a line is that the length continues on forever.You can only find the length of a line segment.
You measure it.
multiply the chord length and radius and divide by 2

Use this method.
-- Find the distance between the endpoint and the midpoint.-- Double that distance to get the length of the complete segment.-- When you're finished, sit quietly for a moment and ponder the meaning of "midpoint".
Find the length of the segment with endpoints of (3,2) and (-3,-6).
