WebFor constructing a circumcircle of a triangle, we need to find construct perpendicular bisectors on either side of the triangle that intersects at a point called the circumcenter of the circumcircle. The three simple … The spherical law of sines deals with triangles on a sphere, whose sides are arcs of great circles. Suppose the radius of the sphere is 1. Let a, b, and c be the lengths of the great-arcs that are the sides of the triangle. Because it is a unit sphere, a, b, and c are the angles at the center of the sphere subtended by those arcs, in radia…

How to find the incircle and circumcircle for an irregular polygon?

WebCalculating the area of a triangle is an elementary problem encountered often in many different situations. The best known and simplest formula is = /, where b is the length of the base of the triangle, and h is the height or altitude of the triangle. The term "base" denotes any side, and "height" denotes the length of a perpendicular from the vertex opposite the … WebThis is because the circumcircle of \(BHC\) can be viewed as the Locus of \(H\) as \(A\) moves around the original circumcircle.
