## How do you find centroid?

Centroid of a Triangle

- Definition: For a two-dimensional shape triangle, the centroid is obtained by the intersection of its medians.
- The centroid of a triangle = ((x1+x2+x3)/3, (y1+y2+y3)/3)
- To find the x-coordinates of G:
- To find the y-coordinates of G:

### How do you find the centroid of a shape?

To calculate the centroid of a combined shape, sum the individual centroids times the individual areas and divide that by the sum of the individual areas as shown on the applet. If the shapes overlap, the triangle is subtracted from the rectangle to make a new shape.

#### What is the centroid of a right triangle?

The centroid of a right angle triangle is the point of intersection of three medians, drawn from the vertices of the triangle to the midpoint of the opposite sides.

**Where is the Circumcenter located in a right triangle?**

If it’s an acute triangle the circumcenter is located inside the triangle. If it’s a right triangle the circumcenter lies on the midpoint of the hypotenuse (the longest side of the triangle, that is opposite to the right angle (90Â°).

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

The centroid of a triangle is the point at which the three medians meet. A median is the line between a vertex and the midpoint of the opposite side. The circumcenter is also the center of the circle passing through the three vertices, which circumscribes the triangle.

## Is centroid equidistant from vertices?

These lines intersect at a point in the middle of the triangle, and this point is called the centroid G. In other words, it is the point that is equidistant from all three vertices.

#### What will be the center of gravity of a circle of radius 10 cm?

Here it will be at 10cm. Explanation: The whole weight of a circle can be assumed to act through its center. So the center of gravity of a circle is at its center. Whatever may be the radius of the circle the center of gravity will be on its center.

**What is the center of gravity of a thin lamina?**

The center of mass is also known as the center of gravity if the object is in a uniform gravitational field. If the object has uniform density, the center of mass is the geometric center of the object, which is called the centroid. Figure 15.6. 1 shows a point P as the center of mass of a lamina.

**What is the area of the lamina?**

Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane.

## What’s a lamina?

1 : a thin plate or scale : layer. 2 : either of two broad, flat plates of bone of a vertebra that is fused with and extends from the pedicle to the median line of the neural arch to form the base of the spinous process and that along with the pedicle forms the posterior part of the vertebral foramen.
