Circumcircle theorems
WebThe diameter of the circumcircle is given by the formula: where a is the length of one side, and A is the angle opposite that side. This gives the diameter, so the radus is half of … In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polygon has a circumscribed circle. A polygon that does have one is called a cyclic polygon, or sometimes a concyclic polygon because its vertice…

Simson-Wallace lines.The pedals 1 of a point M on the lines BC, CA, AB are collinear if and only if M lies on the circumcircle Γ of ABC.In this case, the Simson-Wallace line passes through the midpoint of the segment joiningM to the orthocenter H of triangle ABC.The point M is the isogonal …
WebFeb 20, 2024 · Another formula that may be used to find the circumradius is Euler's Theorem: If d=distance between the incenter and the circumcenter, R= circumradius, and r=inradius, d^2 = R (R-2r). How do you... 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…
WebThe circumcenter is also the centre of the circumcircle of that triangle and it can be either inside or outside the triangle. Circumcenter Formula P(X, Y) = [(x 1 sin 2A + x 2 sin 2B + x 3 sin 2C)/ (sin 2A + sin 2B + sin 2C), (y 1 … WebHyperbolic Circumcircle Theorem For fixed A,B, a point C is such that there is a hyperbolic circle through A,B and C if and only if C lies in exactly one of the horocycles through A and B. There is a CabriJava applet which illustrates the result. We can also tackle the problem algebraically, characterizing the triangles which do
WebThe centers of the incircle and excircles of a triangle form an orthocentric system. The nine-point circle created for that orthocentric system is the circumcircle of the original triangle. The feet of the altitudes in the orthocentric system are the vertices of the original triangle.
