Midpoint Formula

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

For this geometry worksheet students use the midpoint formula to determine the midpoint of a line segment given the end points.  The one page worksheet contains eight problems.  Answers provided. 

In this midpoint formula learning exercise, students find the midpoint of line segments. Students identify the midpoint from information given on a graph and from ordered pairs representing the endpoints. They solve 14 problems on two...

In this midpoint formula worksheet, students determine the midpoint of a line by using given ordered pairs. Students use one endpoint of a line and the midpoint to find the remaining endpoint of a line. This four-page worksheet contains...

It's about to get 3-D! The video shows your class how to expand the midpoint formula to find the midpoint of a three-dimensional segment. The example shown calculates the midpoint using the x-, y-, and z-coordinates.

Let's meet in the middle. Given two points on the coordinate plane, pupils use the interactive to find the midpoint. The interactive provides a graphical display of the midpoint and the midpoint formula with the coordinates of the...

By selecting the resource, you're already halfway to understanding midpoints. Pupils use a slider to locate midpoints on the coordinate plane. They connect this conceptual understanding to the formula for the midpoint of a line segment.

In response to a student question, the "question corner" mentions two different methods to prove that the Midpoint Formula truly does work.

Distance and midpoint formulas are explained through the use of examples and a video lesson. [1:58]

Don't leave your geometry knowledge only halfway complete. An informative video shows how to find the midpoint of a line segment. It introduces the midpoint formula and explains how to use the formula to find the midpoint given the...
