In geometry, the midpoint of a line segment is the point that divides the segment into two equal parts. It is located exactly halfway between the endpoints of the segment. If you have two endpoints, \( A(x_1, y_1) \) and \( B(x_2, y_2) \), the coordinates of the midpoint \( M \) can be calculated using the formula:
\[ M \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]
This gives you the average of the x-coordinates and the average of the y-coordinates of the endpoints.
