In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid of both the segment and of the endpoints. Distance is the length of the line segment between any two points on a coordinate plane. Use this math worksheet to find the midpoint and distance between any two points on a coordinate plane.

Midpoint and distance formula worksheet (with answer key)
Let’s review the definitions of the midpoint and distance formula.
Midpoint: A midpoint is the center of a line segment, that is, the point on the line segment at the same distance from the end points. The midpoint of the line segment between points 
Distance formula: The distance between two points in a coordinate plane is the length of the line segment between them. The distance between two points can be calculated using the formula:
Example 1: Finding the midpoint between two points.
Let’s find the midpoint between the points A
Step 1: Identify the coordinates of the two points.
For point A, we see that 
For point B, we see that 
Step 2: Apply the midpoint formula.
Recalling the midpoint formula of two points, the midpoint between points A
and B
Example 2: Finding the endpoint of the line segment given the midpoint and the other endpoint.
Let’s find the endpoint of the line segment having midpoint M
other endpoint A
Step 1: Identify the coordinates of the known point and the midpoint.
For the endpoint A, we set 
For the midpoint M, we set 
Step 2: Identify the unknown endpoint.
We need to find the other endpoint B
Step 3: Apply the midpoint formula and solve for the unknown endpoint.
Recalling the midpoint formula for two points, we can set
This gives us the following two equations for the coordinates of the midpoint
Substitute the coordinates of the midpoint and the known point.
Solve these two equations for the coordinates of the unknown endpoint B
B
Example 3: Finding the distance between two points.
Let’s find the distance between two points A
Step 1: Identify the coordinates of the endpoints.
For point A, we see that
For point B, we see that
Step 2: Apply the distance formula.
Recalling the distance formula between two points, the distance between points

Real life problem:
Maryville is located at the coordinates 
Since Blaxberg is midway between Maryville and Silly town, find the midpoint of
the coordinates of Maryville and Silly town using the midpoint formula
Blaxberg is located at 
Now, the distance from Maryville to Blaxberg is the distance between the points
The distance from Maryville to Blaxberg is 3 units.
