Lines and circles are the most elementary figures of geometry − a line is the locus of a point moving in a constant direction, and a circle is the locus of a point moving at a constant distance from some fixed point − and all our constructions are done by drawing lines with a straight edge and circles with compasses. For the obtuse-angled triangle, the orthocenter, circumcenter, both lie outside of the triangle and the centroid lies inside of the triangle.Most geometry so far has involved triangles and quadrilaterals, which are formed by intervals on lines, and we turn now to the geometry of circles. In an equilateral triangle, the orthocenter, circumcenter, and the centroid, all lie at the same point, inside of the triangle. Centroid always lies in between the orthocenter and the circumcenter of the triangle. Orthocenter, circumcenter, and centroid always lie in a straight line, known as the Euler's line. What is the Relationship Between the Orthocentre, Circumcentre, and Centroid of Triangle? We can construct the medians of a triangle and mark their intersection point as the centroid or we can use the formula to find the centroid of a triangle. How do You Find the Centroid of a Triangle? The formula for the centroid of the triangle is:Ĭ(x,y) = ((x 1 + x 2 + x 3)/3, (y 1 + y 2 + y 3)/3), where, x 1, x 2, and x 3 are the 'x-coordinates' of the vertices of the triangle and y 1, y 2, and y 3 are the y-coordinates of the vertices of the triangle. If the vertices of the triangle are known to us, we use the following formula to calculate the centroid of a triangle. How do You Find the Centroid of a Triangle When the Vertices are Given? If we construct the medians of a triangle, the point where the medians intersect is the centroid of the triangle. Where is the Centroid of Any Given Triangle Located?Ĭentroid is the intersection of the medians of a triangle. This will be the centroid of the given triangle. Add the y-coordinates of all the three vertices and divide the sum by 3.Add the x-coordinates of all the three vertices and divide the sum by 3.Identify and list all the three coordinates of each vertex.There are three basic steps that can be followed to find the centroid of a triangle: What is the Easiest Way to Find the Centroid of a Triangle? The centroid of a triangle is always within a triangle.The medians are divided into a 2:1 ratio by the centroid.It is the point of intersection of all the three medians of a triangle.The centroid is also known as the geometric center of the object.The properties of a centroid are as follows: The centroid of a triangle is formed when three medians of a triangle intersect. What are the Properties of Centroid of Triangle? The formula used to calculate the centroid of the triangle is: C(x,y) = ((x 1 + x 2 + x 3)/3, (y 1 + y 2 + y 3)/3), where, x 1, x 2, and x 3 are the 'x-coordinates' of the vertices of the triangle and y 1, y 2, and y 3 are the y-coordinates of the vertices of the triangle. What is the Formula for the Centroid of Triangle? It is one of the four points of concurrencies of a triangle. 1.ĭifference Between Orthocentre and Centroid of a Triangleĭifference Between Incentre and Centroid of a TriangleįAQs on Centroid of Triangle What is the Centroid of Triangle? Let us learn more about the centroid of a triangle along with a few solved examples and practice questions. In this article, we will explore the concept of the centroid of a triangle, also commonly called centroid, along with its formula, and its properties. The centroid always lies inside a triangle, unlike other points of concurrencies of a triangle. The point of intersection of the medians of a triangle is known as centroid. Each median of a triangle divides the triangle into two smaller triangles that have equal areas. Medians are the line segments that are drawn from the vertex to the mid-point of the opposite side of the vertex. Before understanding the point of concurrency, let us discuss the medians of a triangle. The centroid of a triangle is a point of concurrency of the medians of a triangle.
