Givin the coordinate of one endpoint of segment AB and its midpoint find the coordniates of the other endpoint?

If the coordinate of A is x, and that of the midpoint of AB, M, is m then
the distance AM is m-x so the distance AB = 2*(m-x)
So the coordinate of B is x + 2*(m-x) = 2m-x
For coordinates in more than one dimension, apply the above rule separately for each dimension.

Which of these segments has an endpoint c and midpoint b?
A+ = segment C A
How do you find the length of a segment when given the endpoint and midpoint?
double the length
How do you find the endpoint of a line segment?
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 - 86 = xY COORDINATE--------------------1 = y1 + 10 / 2-2 = y1 + 10-12 = y
Does a line segment have two midpoints?
No. The midpoint of a line segment is the single point exactly halfway between each endpoint.
If the midpoint of xy is located at the origin and one endpoint of this segment has coordinates of -8 10 what are the coordinates of the other endpoint?
The other end point is (8,-10).
How do you find an endpoint if you are given one endpoint and the midpoint?
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).
Which method could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoint at 0 0 and 0 15?
Each coordinate of the midpoint of a straight line segment is the arithmetic mean of the coordinates of the endpoints. So the y-coordinate is (0+15)/2 = 7.5
How do you find the coordinate of the midpoint of a line segment?
The 'x' coordinate of the midpoint is the average of the 'x' coordinates of the segment's ends. The 'y' coordinate of the midpoint is the average of the 'y' coordinates of the segment's ends.
What is the other endpoint of the line segment with the given endpoint and midpoint. Endpoint (6-9) midpoint (76)?
If you mean endpoint (6, 9) and midpoint (7, 6) then the other endpoint is (8, 3)
How could you find the y-coordinate of the midpoint of a vertical line segment with endpoint at (00) and (015)?
If you mean endpoints of (0, 0) and (0, 15) then the midpoint is at (0, 7.5)
How do you find the missing endpoint of a segment with an endpoint and a midpoint?
The direction of missing endpoint is the same as the direction from the known end point to the midpoint. The distance from the midpoint to the missing endpoint is the same as the distance from the known end point to the midpoint. In coordinate geometry it is simple. If the known end point is (p, q) and the mid point is (r, s) then the missing point is (2r - p, 2s - q).
What is the other endpoint of the segment with midpoint -3 and endpoint -7?

What is an endpoint in geometry?
A line segment has endpoints and a midpoint.
How do you find the length of the segment if you know an endpoint and the midpoint?
-- 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".
Which of these segments has an endpoint c and midpoint b?
A+ = segment C A
What is the coordinate of the midpoint of segment AD?
-2.5
How do you find the length of a segment when given the endpoint and midpoint?
double the length
