So for now, straight to the midpoint formula. So what is the definition of midpoint formula? Well, the midpoint formula is a system that is used in geometry and related subjects to get the exact center of a line connecting two end points. It can also represent a line that flows in three dimensions.

Take hypothetical end points in a graph (x1,y1) and (x2,y2). The mean of these points is actually the center of the line. The exact center of the line is mathematically presented as follows:

M = (x1+x2)/2 , (y1 + y2)/2

The midpoint is also a point in the line that comes at the exact center.

This formula can also be used in the implementation of the center lines in the 3rd dimension. For instance, a line connecting 2 points in a 3D plane can have a mid-point as follows.

Supposing that we had two points in a 3D plane such that :

Point 1 = x1, y1, z1

Point 2 = x2, y2, z2

We can deduce the midpoint to be:

M = (x1 + x2 )/2, (y1 + y2 )/2, (z1 + z2 )/2,

Using this illustration, it thus becomes clear that given any two point in the 2D or 3D plane, it’s very easy to come up with a midpoint. The essence of the midpoint formula is to find the center of the mass, get the centermost area in an economic graph, get the median etc. We apply this knowledge in the academia, in science, in arts and also in research. Many geometrical concepts in the 2D and the 3D planes can however be extrapolated into the higher dimensions and used effectively to predict phenomena and multivariate situations.

What Is The Midpoint Formula

What Is The Definition Of Midpoint Formula

The midpoint formula is as follows for different 1, 2, and 3 dimensional formations.

For a single dimensional plane, the midpoint formula us as follows:

Midpoint (A,B) = (a + b ) /2

For a 2 dimensional plane:

Midpoint (A,B) = (a1+a2)/2 , (b1+b2)/2

For a 3 dimensional plane we have:

Midpoint (A,B) = (a1+a2)/2 , (b1+b2)/2, (c1+c2)/3

For a generalized formula of the midpoint in any dimension, then we have:

Midpoint (A,B) = (A+B)/2 for all values of a and b in the equation.

To get the ith value of the midpoint then we have:

Ith = (ai + bi)/2

Midpoint Formula Example

What Is The Definition Of Midpoint Formula

For those looking for a generalized example f what the midpoint formula is all about, study this diagram carefully.

We have points (-2, 1) and (5,4) as A and B. Essentially the midpoint must be a point at the center of both points.

By applying the midpoint formula we have the following:

Mid (AB) = (A + B)/2

Thus the Mid = [(-2+5)/2 , (1+4)/2] = {1.5, 2.5}

By visual inspection of the graph and Cartesian plane, this is actually accurate.

Distance Formula

What Is The Definition Of Midpoint Formula

The distance formula is another important part of the geometry of graphs. We use it to get the distance between the two points in a graph. Essentially, we have the midpoint formula as the definition of the geometrical center of an item, but the distance formula is the measure of the length from one place to the other.

Having this is mind, it would be great to dive in and see what the formula is:

First of all, if we have a two points say (x1,y1) and (x2,y2) then the way to get the distance is using this formula.

Distance = root( (7-3)^2+(4-7)^2)

Based on this we get Distance as being =  root(25)= 5

Definition Of Midpoint In Geometry

The definition of midpoint in geometry is the exact point hat falls at the exact center between two points in a plane. The midpoint can be considered in a 3D plane as well as in a 2D lane and even higher dimensions. For regular objects with known mathematical formula and formations, we can get generalized ways of getting the midpoint. However, irregular objects will require an individual consideration on a case by case basis.

Slope Formula

What Is The Definition Of Midpoint Formula

The slope formula is used on any two random ordered pairs to get the gradient or the rate of rise between the two pairs. For instance, if we have a point x1,y1 and another point x2,y2 then we can calculate the gradient or the slope between the two points easly. The gradient simple answers the question of how fast the curve rise does or how fast does the curve fall. For rising curves, the gradient is always positive while for falling curves, the gradient is always negative.  

Lets for instance assume that the point 1 is 3,4 while the point 2 is 6,10. We sek to see how fast the curve is rising. By applying the slope formula, we get the following:

 = M = 5/3 = 1.666

It means that for every unit of rise in X the Y will rise by 1.66

Midpoint Formula Economics

What Is The Definition Of Midpoint Formula

In economics, we have a huge array of applications of the midpoint formula. The major one of course comes to when we want a non-variant coefficient of elasticity. The elasticity of a variable can be determined using many different models. However, when using the midpoint formula, the answer is consistent and more filtered for market noise than the other methods. This explains why the economic midpoint formula is applied in a very wide variety of markets, to give accurate and consistent states of elasticity.

Midpoint Formula Geometry

Mathematically, geometry does not just require the midpoint to be found in regular planes. There exists other planes such as circles and parabolas where the midpoint is also necessary to get. Below are some considerations of popular midpoint functions in geometry:

The Midpoint in a circle

The midpoint of a circle is the origin of the radius. This can also be described as the intersection of any two lines perpendicular to the circumference.

The Midpoint in an ellipse

The midpoint of an ellipse is either the intersection of two area bisectors and perimeter bisectors. An ellipse is generally a flattened circle and thus any line radius that divides the area into two or any chord that splits the perimeter into two halves s considered a midpoint. Midpoint theory in Ellipses can be applied in planetary motion or in comet motion. They are the basis of Kepler’s laws of planetary orbiting.

The Midpoint in a hyperbola

When we seek a midpoint in a 2D hyperbola, then the stakes are higher than the circle or the ellipse. Simply put, the midpoint of the hyperbola is the intersection of the midpoint of the hyperbola vertices.

The Midpoint in a triangle

The center or the midpoint of a triangle is the intersection of all the inner angles of the triangle. The midpoint is achieved where all the three angle bisectors meet at the center of the triangle. This geometrical theory has application in engineering, as well as the science of materials, in the construction of weight-sensitive planes.

The Midpoint in a quadrilateral

To get the midpoint of a regular quadrilateral, then s is a matter of two steps. First get the midpoint of both pairs of opposite sides. Secondly, connect the midpoints of the opposite sides to each other. The midpoint is the intersection.

The Midpoint in a polygon

The midpoint in polygons can be a bit complicated. The first thing to note is that we can only predict the midpoint of regular polygons.

For a regular polygon, the origin of the inscribed circle is the midpoint. This circle can be described as the circle that takes all the sides of the polygon as tangents to its circumference.
