## Can the centroid circumcenter and orthocenter are collinear?

Triangle centers on the Euler line Euler showed in 1765 that in any triangle, the orthocenter, circumcenter and centroid are collinear. In equilateral triangles, these four points coincide, but in any other triangle they are all distinct from each other, and the Euler line is determined by any two of them.

**Can the centroid circumcenter and orthocenter be the same?**

Thus from Altitude, Median and Perpendicular Bisector Coincide iff Triangle is Isosceles, the altitude from AB, the midpoint of AB and the perpendicular bisector of AB are all different. So the circumcenter, centroid and orthocenter of △ABC likewise cannot be the same point.

**For what triangles is it true that the circumcenter and the centroid are the same point?**

Only with an equilateral triangle will the centroid, circumcenter, incenter and orthocenter always be the same point!

### In which triangle is the centroid and orthocentre the same point?

equilateral triangle

In equilateral triangle orthocentre and centroid lie at the same point. Hence option [D] is the right answer.

**How do you prove the orthocentre circumcentre and centroid are collinear?**

Let the points and represent the orthocentre, centroid and circumcentre. The orthocentre, centroid and circumcentre always lie on a straight line with the centroid between the other two. and are collinear. The distance between the centroid and orthocentre is twice the distance between the centroid and circumcentre.

**What is the relation between orthocentre circumcentre and centroid?**

Theorem 1 The orthocentre, centroid and circumcentre of any trian- gle are collinear. The centroid divides the distance from the orthocentre to the circumcentre in the ratio 2:1. The line on which these 3 points lie is called the Euler line of the triangle.

#### Is circumcentre and Orthocentre same?

Orthocentre of a triangle: The point of concurrency of the altitudes of a triangle is known as the orthocentre of the triangle. Circumcentre of a triangle: The point of intersection of the perpendicular bisector of the sides of a triangle is known as circumcentre of the triangle.

**What is the relation between Orthocentre circumcentre and centroid?**

**What is the relation between Orthocentre Circumcentre and centroid?**

## What is the different between an orthocenter and a centroid?

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.

**What is the difference between centroid and orthocenter of a triangle?**

The centroid of a triangle is the point at which the three medians meet. The orthocenter is the point of intersection of the altitudes of the triangle, that is, the perpendicular lines between each vertex and the opposite side.

**What is the position of Orthocentre and centroid in the following triangles a right angled triangle B obtuse angled triangle?**

The orthocenter of a triangle is the point where the perpendicular drawn from the vertices to the opposite sides of the triangle intersect each other. For an acute angle triangle, the orthocenter lies inside the triangle. For the obtuse angle triangle, the orthocenter lies outside the triangle.

### Is the orthocenter of a right triangle always collinear?

Not only in right triangle but in all triangle. The orthocenter H, the circumcenter O, and the centroid G of any triangle are collinear, i.e. they all lie on one line. Furthermore, G is between H and O (unless the triangle is equilateral, in which case the three points coincide) and HG = 2GO.

**Is the centroid of a triangle collinear with the circumcenter?**

For a triangle , let be the centroid (the point of intersection of the medians of a triangle), the circumcenter (the center of the circumscribed circle of ), and the orthocenter (the point of intersection of its altitudes). Then , , and are collinear and . Note that and can be located outside of the triangle.

**Where is the centroid of a right triangle located?**

Centroid (G) is always located in the interior of a triangle. Where as, in obtuse triangles only, circumcenter (C) and orthocentre (H) lie outside the triangle. In right triangles, it lies at the midpoint of hypotenuse. The centroid (G), the orthocenter (H) and the (C) are collinear.

#### What is the difference between circumcenter and orthocenter?

Circumcenter: The circumcenter is the center of a triangle’s circumcircle. It can be found as the intersection of the perpendicular bisectors Orthocenter: The orthocenter is the point where the three altitudes of a triangle intersect. A altitude is a perpendicular from a vertex to its opposite side
