# Calculating the midpoint of a line segment

Last updated: September 30, 2021

## Introduction

In geometry, the midpoint is the centre point of a straight line. In a straight line, the midpoint is equidistance (equal distance) from both ends of the straight line. The midpoint of a straight line is the centroid of the line segment, which gives the exact centre point in a line segment. A midpoint bisects (cuts in half) a line. Let $$AB$$ be a straight line, and $$M$$ be the midpoint of $$AB$$. Then, $$AM=BM$$.
