# How do you find the centroid of a trapezoid?

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

A trapezoid’s centroid is located halfway between the two bases. Let’s look at a few examples of the centroid of a trapezoid formula. A trapezoid is a four-sided quadrilateral with two parallel sides. A trapezoid’s centroid is located halfway between the two bases.

**Where is CG of a trapezoid?**

Trapezoid. The center of gravity of a trapezoid can be estimated by dividing the trapezoid in two triangles. The center of gravity will be in the intersection between the middle line CD and the line between the triangles centers of gravity.

### What is the formula for a trapezoidal?

The formula that is used to find the area of a trapezoid is expressed as, Area of trapezoid = ½ (a + b) h; where a’ and ‘b’ are the bases (parallel sides) and ‘h’ is the height of the trapezoid.

**What is CG of triangle?**

The centroid or Centre of Gravity of a triangle is the intersection of the three medians of the triangle (each median connecting a vertex with the midpoint of the opposite side).

## What is a triangle centroid?

The geometric centroid (center of mass) of the polygon vertices of a triangle is the point (sometimes also denoted ) which is also the intersection of the triangle’s three triangle medians (Johnson 1929, p. 249; Wells 1991, p. 150). The point is therefore sometimes called the median point.

**What is the volume of a trapezoid?**

Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

### 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.
