Triangles have multiple centers
WebThe center of the incircle is located at the point of intersection of triangle bisectors. The center of the circumcircle is located at the point of intersection of three lines perpendicular to triangle sides and crossing ... If two triangles have two sides equal, respectively, and the angles between the two sides are equal too, then the ... WebEach triangle center has an elegant function for the barycentric or trilinear coordinates of the point. So far, no corresponding elegant set of functions for the tetrahedral centers is known. Ideally, given the four face areas, four face perimeters, four solid angles, four vertex altitudes, four exspheres, six dihedral angles, six edge lengths or 12 face angles, some …

WebDec 11, 2024 · This works out perfectly: The measure of each internal angle of an equilateral triangle is 60 degrees, and 6 × 60 = 360, which is exactly what we need around a single point. Similarly for squares: Four squares around a single point at 90 degrees each gives us 4 × 90 = 360. But starting with pentagons, we run into problems.

WebSo, we have two triangles, one with length of sides $13$, $14$ and $15$, and another with length of sides $13, 14$ and $15.2$. By SSS theorem, two triangles are congruent if and only if length of all sides of the first triangle corresponding length of sides of the other triangle.
