WebSo that is the perimeter of P and it looks like we're done. The area of our triangle ABC is equal to 1/2 times r times the perimeter, which is kind of a neat result. 1/2 times the inradius times the perimeter of the triangle. Or sometimes you'll see it written like this. It's equal to r times P over s-- sorry, P over 2. WebIn geometry, a triangle center or triangle centre is a point in the triangle's plane that is in some sense in the middle of the triangle. For example, the centroid, circumcenter, incenter and orthocenter were familiar to the ancient Greeks, and can be obtained by simple constructions.. Each of these classical centers has the property that it is invariant (more …
