How do you calculate the centroid of a trapezium when using geometic picture
A regular decagon can be divided into triangles by drawing diagonals from one vertex to all other non-adjacent vertices. This method results in a total of 8 triangles. Alternatively, using the formula for the number of triangles formed in a polygon, which is ( n - 2 ) (where ( n ) is the number of sides), a decagon (10 sides) can be divided into ( 10 - 2 = 8 ) triangles.
The maximum number of parts a circle can be divided into by using ( n ) straight lines is given by the formula ( \frac{n(n + 1)}{2} + 1 ). For 100 straight lines, this calculation becomes ( \frac{100(100 + 1)}{2} + 1 = 5051 ). Thus, with 100 straight lines, the maximum number of parts a circle can be divided into is 5051.

draw a big triangle then make a line halfway through it
Suppose the base and parallel sides of the trapezium are labelled a and b. Suppose, also, that the distance between a and b is h. Draw a diagonal. This will split the trapezium into one triangle whose base is the trapezium's base (a) and another upside-down triangle whose base is the trapezium's top (b). The heights of both these triangles will be the same as the distance between the parallel sides of the trapezium (h). The area of the first triangle is 0.5*a*h The area of the second triangle is 0.5*b*h So the area of the trapezium = 0.5*a*h + 0.5*b*h = 0.5*(a+b)*h

The altitudes of a triangle are the segments drawn from each vertex perpendicular to the opposite side. These lines intersect at a point called the orthocenter, which can lie inside the triangle for acute triangles, on the vertex for right triangles, and outside for obtuse triangles. Each altitude represents the height of the triangle from that vertex, contributing to the calculation of the triangle's area. The altitudes can be constructed using geometric methods or calculated using coordinate geometry.
Yes, any polygon can be composed using only triangles.
