You can also practice using the midpoint formula worksheet.
The following diagram shows how to use the midpoints formula to find the midpoint for the two points (x1,y1) and (x2,y2). Scroll down the page for more examples and solutions on how to use the midpoint formula.
When learning about midpoints, it is also important to understand the concept of congruent segments. Congruent line segments are line segments with the same length. In a line segment, there is one point that will bisect the line segment into two congruent line segments. This point is called the midpoint.
How to identify, define and label a midpoint?
By using x and y coordinates, it is easy to find the midpoint of a line segment. Finding the midpoint is calculated by taking the average of the x coordinates and then taking the average of the y coordinates. For example, if we had two coordinates located at (1,3) and (5, 7) our midpoint would be (3, 5).

In Geometry, a plane is any flat, two-dimensional surface. Two planes that do not intersect are said to be parallel. Parallel planes are found in shapes like cubes, which actually has three sets of parallel planes. The two planes on opposite sides of a cube are parallel to one another.

The plural forms of vertex, vertices are typically intersections or corners in figures. In an angle, the vertex is where two lines, rays, or segments meet. A diagonal is a line segment whose endpoints are vertices. In a polygon, a vertex is where two edges or sides meet. In a polyhedron, a vertex is where three edges meet.
