Introduction

The midpoint of a line segment is the point that divides the line segment into two equal parts. It is an essential concept in geometry and is used to find the midpoint of a line segment joining two points. In this article, we will learn how to find the midpoint of a line segment joining two points.

What is a Midpoint?

A midpoint is a point that divides a line segment into two equal parts. It is the point that is equidistant from the two endpoints of the line segment. The midpoint formula is used to find the midpoint of a line segment joining two points.

Midpoint Formula

The midpoint formula is given by:

\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)

where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two points.

Finding the Midpoint of a Line Segment Joining Two Points

To find the midpoint of a line segment joining two points, we need to use the midpoint formula. Let's consider an example to understand how to use the midpoint formula.

Example

Find the midpoint of the line segment joining the points $A(2, -7)$ and $B(2, 1)$ .

Step 1: Identify the Coordinates of the Two Points

The coordinates of the two points are $A(2, -7)$ and $B(2, 1)$ .

Step 2: Apply the Midpoint Formula

To find the midpoint, we need to apply the midpoint formula. We will substitute the coordinates of the two points into the midpoint formula.

\left(\frac{2+2}{2},\frac{-7+1}{2}\right)

Step 3: Simplify the Expression

Now, we need to simplify the expression to find the midpoint.

\left(\frac{4}{2},\frac{-6}{2}\right)

\left(2,-3\right)

Conclusion

The midpoint of the line segment joining the points $A(2, -7)$ and $B(2, 1)$ is $(2, -3)$ .
