Use the midpoint formula.
( x1 + x2 / 2 , y1 + y2 / 2 )
For example, if you were given segment QR with midpoint M(-1, -1) and endpoint Q(-8, 10):
(-1, -1) = ( x1 + -8 / 2 , y1 + 3 / 2)
X COORDINATE
-------------------
-1 = x1 + -8 / 2
-2 = x1 - 8
6 = x
Y COORDINATE
-------------------
-1 = y1 + 10 / 2
-2 = y1 + 10
-12 = y
The line segment is a radius.
The segment you describe is the radius of the circle.
A line segment is a straight line that has an endpoint on both sides (look below). ----
Yes, I do understand the definition of a line segment. A line segment is a line that actually has two endpoints. Such endpoint is a triangle's or a square's side.
It is the point at which a line segment ends!
Such a line segment would be a radius of the circle.
The line segment is a radius.
A line segment has two endpoints
If you are only given one endpoint and a midpoint, you know what the middle of the line segment is. Since the midpoint is half of what the line segment's length is, all you have to do is find the distance between the endpoint given and the midpoint, then add that coordinate to your midpoint and get your other endpoint. For example: Endpoint A: (4,5) Midpoint: (6,8) Distance between: (2,3) Add (2,3) to (6,8) and get Endpoint B: (8,11).
The segment you describe is the radius of the circle.
No its not the same
It has two endpoints. A ray has one endpoint.
That's a 'line segment'.

There are only three endpoint given and these are not sufficient to define a segment of a line.
At the end of the line there needs to be two points. Measure the line and divide by two.
By definition a line has no endpoint as it can extend to negative and positive infinity. A ray has one endpoint and a segment has two endpoints.
