Midpoint `(x_M, y_M)` | `=(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2})` |

`=(\frac{0 + 8}{2}, \frac{2 + 8}{2})` | |

** Midpoint of a line segment calculator** uses coordinates of two points `A(x_A,y_A)` and `B(x_B,y_B)` in the two-dimensional Cartesian coordinate plane and find the halfway point between two given points `A` and `B`. It's an online Geometry tool requires `2` endpoints in the two-dimensional Cartesian coordinate plane. It's an alternate method to finding the midpoint of a line segment without compass and ruler.

It is necessary to follow the next steps:

- Enter coordinates (`x_A`,`y_A`) and (`x_B`,`y_B`) of two points A and B in the box. These values must be real numbers or parameters;
- Press the "
**GENERATE WORK**" button to make the computation; - Midpoint calculator will give the coordinates of the midpoint `M (x_M , y_M )` of the line segment `overline{AB}`.

If we have coordinates of two points `A(x_A,y_A)` and `B(x_B,y_B)`, then the midpoint of the line segment `overline{AB}` is determined by the formula

`M(x_M,y_M)\equiv M(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2})`

As we know, a line segment `overline{AB}` is a part of the line that is bound by two distinct points `A` and `B`, which are called the endpoints of the line segment `overline{AB}`. The point `M` is the midpoint of the line segment `overline{AB}` if it is an element of the segment and divides it into two congruent segments, `overline{AM}\congoverline{MB}`. Each segment between the midpoint M and an endpoint have the equal
length. It is often said that the point M bisects the segment `overline{AB}`. In other words, the midpoint is the center, or middle, of a line segment. Any line segment has a unique midpoint. So, we can find the midpoint of any segment on the coordinate plane by using the mipoint formula.

The x-coordinate of the midpoint M of the segment `overline{AB}` is the arithmetic mean of the x- coordinates of the endpoints of the segment `overline{AB}`. Similarly, the y-coordinate of the midpoint M of the segment `overline{AB}` is the arithmetic mean of the y-coordinates of the endpoints of the segment `overline{AB}`.

The midpoint work with steps shows the complete step-by-step calculation for finding the coordinates of center point of line segment having 2 end points A at coordinates (5,8) and B at coordinates (3,2). For any other combinations of endpoints, just supply the coordinates of 2 endpoints and click on the "GENERATE WORK" button. The grade school students may use this midpoint calculator to generate the work, verify the results or do their homework problems efficiently.

Because an ordered pair of numbers represents coordinates of a point in the two-dimensional Cartesian plane, the midpoint of a line segment calculator is most often used in analytical geometry. It is also used in other areas of mathematics, especially in the area of complex numbers. For example, a complex number `z = a+ib` corresponds to the ordered pair of numbers `(a, b)`. It means that the midpoint of the segment connecting `z_1 = a + ib` and `z_2 = c + id` in the complex plane is the point `(z_1+z_2)/2` with the coordinates:

$$\Big(\frac{a + c}{2}, \frac{b + d}{2}\Big)$$

The midpoint also has applications in physics. The center of mass of an object, is well known as its center of gravity. In other words, is its point of balance. For instance, the midpoint of a ruler is its point of balance. For any line segment, the midpoint is its point of balance, center of mass or center of gravity.

**Practice Problem 1: **

Belgrade is located at `(44.5^o, 20.3^o)` and Paris is located at `(48.9^o,2.35^o)`, which represent north latitude and west longitude. If Belgrade and Paris are endpoints of a line segment connecting these towns, find the latitude and longitude of the midpoint of this segment.

**Practice Problem 2: **

Find coordinates of the midpoint `M` of `\overline{PQ}`.

The midpoint calculator, formula, example calculation (work with steps) and practice problems would be very useful for grade school students (K-12 education) to learn what is midpoint of a line segment in geometry, how to find it and where it can be applicable in real world problems.
