In surveys or data analysis, finding the midpoint between two values can help figure out trends or create averages. It’s basically the “let’s split this thing evenly” tool for real life.

Learn how to use the midpoint formula to find the midpoint of a line segment on the coordinate plane, or find the endpoint of a line segment given one point and the midpoint.

What problems can I solve with the midpoint formula? Given two points on the plane, you can find their midpoint. For example, let's find the midpoint of (5, 3) and (1, 7) :

Find the midpoint of a segment on the coordinate plane, or find the endpoint of a segment given one point and the midpoint.

In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane. For example, we can see that opposite sides of a parallelogram are parallel …
