Tangent Spheres and Triangle Centers
1. TANGENT SPHERES. Any four mutually tangent spheres determine six points of tangency. We say that a pair of tangencies {ti , t j } is opposite if the two spheres determining ti are distinct from the two spheres determining t j . Thus the six tangencies are naturally grouped into three opposite pairs, corresponding to the three ways of partitioning the four spheres into two pairs. Altshiller-C...
متن کاملSome Configurations of Triangle Centers
Many collections of triangle centers and symmetrically defined triangle points are vertices of configurations. This illustrates a high level of organization among the points and their collinearities. Some of the configurations illustrated are inscriptable in Neuberg’s cubic curve and others arise from Monge’s theorem.
متن کاملThe Locations of Triangle Centers
The orthocentroidal circle of a non-equilateral triangle has diameter GH where G is the centroid and H is the orthocenter. We show that the Fermat, Gergonne and symmedian points are confined to, and range freely over the interior disk punctured at its center. The Mittenpunkt is also confined to and ranges freely over another punctured disk, and the second Fermat point is confined to and ranges ...
متن کاملMore on reverse triangle inequality in inner product spaces
Refining some results of Dragomir, several new reverses of the generalized triangle inequality in inner product spaces are given. Among several results, we establish some reverses for the Schwarz inequality. In particular, it is proved that if a is a unit vector in a real or complex inner product space (H ;〈·,·〉), r,s > 0, p ∈ (0,s], D = {x ∈ H ,‖rx− sa‖ ≤ p}, x1,x2 ∈D−{0}, and αr,s = min{(r2‖x...
متن کاملMore operations, more deaths? Relationship between operative intervention rates and risk-adjusted mortality at trauma centers.
INTRODUCTION The Trauma Quality Improvement Project has demonstrated significant variations in risk-adjusted mortality rates across the designated trauma centers. It is not known whether the outcome differences are related to provider-level clinical decision making. We hypothesized that centers with good outcomes undertake critical operative interventions aggressively, thereby avoiding complica...
