# How do you find the other midpoint when given the endpoint and one midpoint?

i have found the answer dont worry.

### 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…

### How do you find an endpoint if you are given the other endpoint and the midpoint?

You practically just use the midpoint formula. M(x,y)= (x1 + x2, y1 + y2) ---------- -------- (the 2 is part of a fraction for the midpoint formula) ---> 2 2 For ex. The midpoint of JK is (3,4). One endpoint is K(-3,-2). (-3 + y2 , -2 + y2). -------- --------- 2 2 You Multiply the midpoint coordinates to the denominators. So the midpoint coordinate 3 is multiplied to the first denominator and 4 is…

### 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).

### How do you find an endpoint of a line if you are given an endpoint and the midpoint?

Ok. The midpoint formula: [(x1 + x2)/2, (y1 + y2)/2] So for instance if your coordinates were endpoint : (-8,10) and the Midpoint: (-2,6) By substituting the given values into the formula we have: (x1 + -8)/2 = -2 and (y1 + 10)/2 = 6 x1 - 8 = -4 and y1 + 10 = 12 x1 -8 + 8 = -4 + 8 and y1 + 10 - 10 = 12 - 10 x1…

### For a line segment one endpoint is -8 10 and the midpoint of - 2 6 Find the coordinates of the other endpoint x1 y1?

The midpoint is going to have an x and y value halfway between those of the two endpoints. The midpoint has an x value 6 higher than the first endpoint and a y value 4 lower. Just continue this pattern to get the other endpoint. (-2+6, 6-4)=(4, 2) The midpoint formula: [(x1 + x2)/2, (y1 + y2)/2] By substituting the given values into the formula we have: (x1 + -8)/2 = -2 and (y1 +…

### How to find the endpoint if the midpoint and a endpoint is already given?

Ok. The midpoint formula: [(x1 + x2)/2, (y1 + y2)/2] So for instance if your coordinates were endpoint : (-8,10) and the Midpoint: (-2,6) By substituting the given http://wiki.answers.com/Q/How_do_you_find_an_endpoint_of_a_line_if_you_are_given_an_endpoint_and_the_midpoint&firstAnswer=1&updated=1&waNoAnsSet=1&status=T1BUSU1JWkVBTk9OWU1PVVNBTlNXRVJT# into the formula we have: (x1 + -8)/2 = -2 and (y1 + 10)/2 = 6 x1 - 8 = -4 and y1 + 10 = 12 x1 -8 + 8 = -4 + 8 and y1 + 10 - 10 = 12 - 10 x1…

### How do you find the endpoint of a line segment when one endpoint is given and a point one third of the way is given?

There are two possible answers given the information. What isn't given is if the second point is one third of the way from the known or unknown endpoint. Say the known endpoint is (xe,ye) and the point one third of the way along is (xt,yt). If the point one third of the way is closest to the known endpoint, the other endpoint would be (xe+3*(xt-xe), ye+3*(yt-ye)). This is probably the answer implied by your question…

### 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 - 8 6 = x Y COORDINATE ------------------- -1 = y1 + 10 /…

### How do you find the length if you have the coordinates and the midpoint?

To work out the length, you need the coordinates of both endpoints. If you have one endpoint and the midpoint, you can treat this as two endpoints and then double the answer you get to calculating the length. To calculate the length, work out the difference in x axis values and difference in y axis values. You then find the square root of (x2+y2). This is the length between the two coordinates.

### How do you find midpoint of a segment?

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.
