midpoint is given by the formula (x1 +x2) /2 and (y1 +y2) /2 where (x1 ,y1 )and (x2 ,y2) are the end points of the line segment .so if one end point and mid point is given the other end point can be calculated .
A midpoint of anything is the point exactly halfway between the beginning point and the end point. So logically, it is the "midpoint".
Suppose one end point is A and the midpoint is M. Then the distance from the given end to the midpoint is M-A. So the other end point is M-A further away from M ie it is at M + (M-A) = 2M-A. The above answer looks like it is for 1 dimensional problems only but for two or more dimensions, either treat A and M as vectors or (if you are not familiar with vectors), apply the same rule to the x-coordinate, then separately, to the y-coordinate, etc. So, in 2 dimensions, if A = (ax, ay) and M = (mx, my) then the other end point is (2mx- ax , 2my- ay) and similarly for more dimensions.
The midpoint is the point between the beginning and the end, in distance or in time.
A ray has a beginning but no endpoint.
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).
Add the same amount again by finding the difference of the midpoint and end point. Example: If the end point is 3 and the mid point is 9. The difference between 3 and 9 is 6 so add 6 to 9 and get 15.
The other end point is (8,-10).

the endpoint
Suppose one end point is A and the midpoint is M. Then the distance from the given end to the midpoint is M-A. So the other end point is M-A further away from M ie it is at M + (M-A) = 2M-A. The above answer looks like it is for 1 dimensional problems only but for two or more dimensions, either treat A and M as vectors or (if you are not familiar with vectors), apply the same rule to the x-coordinate, then separately, to the y-coordinate, etc. So, in 2 dimensions, if A = (ax, ay) and M = (mx, my) then the other end point is (2mx- ax , 2my- ay) and similarly for more dimensions.
Two collinear rays with the same endpoint form an angle. They share a common initial point and extend in opposite directions. The endpoint where they meet is called the vertex of the angle.
