## What is section formula for external division?

External Divisions with Section Formula P = ( m x 2 − n x 1 m − n , m y 2 − n y 1 m − n ) . P=\left( \dfrac{mx_2 - nx_1}{m-n}, \dfrac{my_2 - ny_1}{m-n} \right) .

## What is coordinate geometry formula?

In coordinate geometry, Section formula is used to find the ratio in which a line segment is divided by a point internally or externally. It is used to find out the centroid, incenter and excenters of a triangle. In physics, it is used to find the center of mass of systems, equilibrium points, etc.

## What is centroid value?

The centroid value is the most complex node centrality index. ... The centroid value suggests that a specific node has a central position within a graph region characterized by a high density of interacting nodes.

## What is the use of centroid?

Real life application of Centroid  Centroids indicate the center of mass of a uniform solid. stick a pivot at the centroid and the object will be in perfect balance.  Lots of construction applications and engineering applications to design things so that minimal stress and energy is used to stabilize a component.

## What is the difference between centroid and Centre of gravity?

Differentiate Between the Center of Gravity and Centroid The difference between the center of gravity and centroid are as follows: (a) The center of gravity is the point where the total weight of the body is focused. Whereas the centroid is the geometrical center of a body.

## Is Orthocentre and centroid same?

The centroid is always between the orthocenter and the circumcenter. ... The orthocenter is always outside the triangle opposite the longest leg, on the same side as the largest angle. The only time all three of these centers fall in the same spot is in the case of an equilateral triangle.

## Is Circumcentre and centroid same?

The centroid of a triangle is the point at which the three medians meet. ... The three perpendicular bisectors of the sides of a triangle meet at the circumcenter. The circumcenter is also the center of the circle passing through the three vertices, which circumscribes the triangle.

## What is the difference between centroid and Orthocenter?

The centroid (G) of a triangle is the point of intersection of the three medians of the triangle. ... The centroid is located 2/3 of the way from the vertex to the midpoint of the opposite side. The orthocenter (H) of a triangle is the point of intersection of the three altitudes of the triangle.

## Can Orthocenter be outside triangle?

It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. The orthocenter is not always inside the triangle. If the triangle is obtuse, it will be outside. To make this happen the altitude lines have to be extended so they cross.

## What centroid means?

In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean position of all the points in the figure. ... The definition extends to any object in n-dimensional space: its centroid is the mean position of all the points in all of the coordinate directions.

## What are the 4 centers of a triangle?

The four ancient centers are the triangle centroid, incenter, circumcenter, and orthocenter.

## What is Orthocentre and Incentre?

Incenter: Where a triangle's three angle bisectors intersect (an angle bisector is a ray that cuts an angle in half); the incenter is the center of a circle inscribed in (drawn inside) the triangle. ... Orthocenter: Where the triangle's three altitudes intersect.

## What does Circumcenter mean?

The circumcenter is the center of a triangle's circumcircle. It can be found as the intersection of the perpendicular bisectors.

## Is the Incenter the center of gravity?

Triangle Centers. Incenter - The intersection of the angle bisectors of the three angles of the triangle. ... Also the center of gravity of the triangle. Euler Line - The line containing the circumcenter, orthocenter, and centroid.

## What is the meaning of Circumcircle?

: a circle which passes through all the vertices of a polygon (such as a triangle)

## What is the radius of Circumcircle?

Then the radius R of its circumscribed circle is R=abc4√s(s−a)(s−b)(s−c). In addition to a circumscribed circle, every triangle has an inscribed circle, i.e. a circle to which the sides of the triangle are tangent, as in Figure 12.

## What is the area of Circumcircle?

Approach: Since the hypotenuse C passes through the center of the circle, the radius of the circle will be C / 2. And we know that the area of a circle is PI * r2 where PI = 22 / 7 and r is the radius of the circle. Hence the area of the circumcircle will be PI * (C / 2)2 i.e. PI * C2 / 4.

## What is Circumcircle and Incircle?

The circumcircle of a triangle is the unique circle determined by the three vertices of the triangle. ... The incircle of a triangle is the circle inscribed in the triangle. Its center is called the incenter (green point) and is the point where the (green) bisectors of the angles of the triangle intersect.

## What is the formula of Inradius?

Calculating the radius Its radius, the inradius (usually denoted by r) is given by r = K/s, where K is the area of the triangle and s is the semiperimeter (a+b+c)/2 (a, b and c being the sides).

## How is Incircle formed?

As can be seen in Incenter of a Triangle, the three angle bisectors of any triangle always pass through its incenter. In this construction, we only use two, as this is sufficient to define the point where they intersect. We bisect the two angles using the method described in Bisecting an Angle.
