# Find the midpoint of the line segment having the given endpoints 8 -4 and -7 8?

(0.5, 2)

### What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment?

To calculate the x-coordinate of the midpoint of a horizontal segment, you simply take the sum of x-coordinate of the endpoints of the horizontal segment and divide this by two. An example is if one is given endpoints with th x and y coordinates 2,3 and 5,6. To find the midpoint of the x-coordinates add 2 and 5 and divide this by 2, or 7/2.

### What methods could you use to calculate the x coordinate of the midpoint of a horizontal segment with the endpoints of -6 0 and 6 0?

You could use algebra (see below for how to do that), or you could graph the line and measure it. Using algebra The x-coordinate of the midpoint of a line segment is the average of the x-coordinates of the end-points. 1/2(-6 + 6) = 0 The y-coordinate of the midpoint of a line segment is the average of the y-coordinates of the end-points. 1/2(0 + 0) = 0 The midpoint of the given horizontal segment…

### The endpoints of a segment are given Determine the midpoint of the segment if C 2 6 and D 4 0?

The midpoint formula is: [(x1 + x2)/2, (y1 + y2)/2]. If we denote the coordinates of the point C as (x1, y1) = (2, 6), and the coordinates of the point D as (x2, y2) = (4, 0), we can find the coordinates of the midpoint by using the above formula. So, [(x1 + x2)/2, (y1 + y2)/2] = [(2 + 4)/2, (6 + 0)/2] = (3, 3)

### 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 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…

### What are secondary parts of a triangle in geometry?

A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC. the secondary parts are at the bottom. the secondary parts of the triangle median - a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side angle bisector - a segment which…

### Basic and secondary parts of a triangle?

A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC. In Euclidean geometry any three non-collinear points determine a unique triangle and a unique plane (i.e. a two-dimensional Euclidean space). the secondary parts of the triangle median - a segment whose endpoints are a vertex of the triangle…

### How do you contrust the mid point of a given line?

First, it needs to be a line segment: a line is infinitely long and so has no midpoint. Suppose the line to be bisected is AB. Place the point of a pair of compasses at A with an arc which is greater than half AB. Draw arcs above and below the line segment. Then, move the compass point to B and without changing the arc width, draw fresh arcs to intercept the previous ones at…

### How many points are in a unique line?

Every line and every line segment of >0 length has an inifinite amount of unique points. Socratic Explaination: consider ... - There are 2 distinct points defining a line segment. - Between these 2 distinct points, there is a midpoint. - The midpoint divides the original segment into 2 segments of equal length. - There are 2 distinct points used to define each segment. - Between these 2 distinct points, there is a midpoint for…

### How do you find the center of the circle given the endpoints of the diameter in coordinate geometry?

First, find the coordinates of the diameter midpoint. For example, the endpoints of a diameter have coordinates of (x1, y1) = (1, 2) and (x2, y2) = (7, 6). By the midpoint formula we have: (xm, ym) = [(x2 - x1)/2, (y2 - y1)/2] = [(7 - 1)/2, (6 - 2)/2] = (3, 2) Since (x1, y1) it is the closest point to the origin, the coordinates of the center of the circle are: (xc…

### 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…

### 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 +…

### Given two points A and B in the three dimensional space what is the set of points equidistant from A and B?

A plane is the set of all points in 3-D space equidistant from two points, A and B. If it will help to see it, the set of all points in a plane that are equidistant from points A and B in the plane will be a line. Extend that thinking off the plane and you'll have another plane perpendicular to the original plane, the one with A and B in it. And the 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 /…
