The midpoint divides a line segment into two equal parts.The midpoint divides a line segment in an equal ratio, that is, 1:1.The following points are the important properties of the midpoints.

the negative sign is used if the point is dividing externally.The positive sign is used in the formula to find the coordinates of the point, which divides the points internally, and.The section formula to find the coordinates of a point, which divides the line joining the points (x 1, y 1), and (x 2, y 2) in the ratio m:n is as follows. The point can be located between the points, or anywhere beyond the points, but on the same line. Further, the ratio in which the point divided the line joining the two given points is needed to know the coordinates of the point. The section formula is helpful to find the coordinates of any point which is on the line joining the two points. For a triangle with vertices (x 1, y 1), (x 2, y 2), (x 3, y 3) the formula to find the coordinates of the centroid of the triangle is as follows. The centroid divides the median of the triangle in the ratio 2:1. The median is a line joining the vertex to the midpoint of the opposite side of the triangle.

The point of intersection of the medians of a triangle is called the centroid of the triangle. The following two formulas are closely related to the midpoint formula. The midpoint formula includes computations separately for the x-coordinate of the points, and the y-coordinate of the points. Let x coordinate of P be m and y coordinate of P be n. If the coordinates of Q are (8, 10), then what are the coordinates for point P? Solve it by using the midpoint formula. Here's an example to find the coordinate of an endpoint, given the midpoint and the coordinates of the other endpoint.Įxample: Midpoint R between the points P and Q has the coordinates (4, 6). The point of intersection of the line connecting the cusps and the segment is the midpoint of the segment. We can use a compass and straightedge construction to first construct a lens using circular arcs of equal (and large enough) radii centered at the two endpoints, then connecting the cusps of the lens (the two points where the arcs intersect). Method 3: One way to find the midpoint of a line given in a plane is by using construction. In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are (/2) = (-2/2, 1/2)= (-1,1/2). The midpoint formula is also used to find the coordinates of the endpoint if we know the coordinates of the other endpoint and the midpoint. The midpoint formula is used to find the midpoint between two points whose coordinates are known to us. Further, if a line is drawn to bisect a line segment joining these two points, the line passes through the midpoint. The midpoint divides the line joining these two points into two equal halves.

The two reference points are the endpoints of a line segment, and the midpoint is lying in between the two points. Midpoint refers to a point that is exactly in the middle of the line segment joining two points.
