Geometric elements in the plane intersecting, lines and circles, can characterize its intersection by a value called angle.
The notion of angle between two lines is the most elementary, and serves as a reference to define the angle between line and circle or two circles forming.
The so-called fundamental problem of tangents may occur with respect tangency conditions of a circle, instead of a straight.
Conceptually we can assume that the above is a particular case of this, if we consider the straight as a circle of infinite radius.
In both cases therefore apply similar reasoning for resolution, based on the concepts learned power.
Classically tangencies problems have been studied looking geometric constructions of each case study.
The concepts of power of a point on a circle can address the problems with a unifying approach, so that any tangency or incidences statement generally be reduced to a more generic fundamental problem tangents denominate (PFT).
Along with the concepts of power, Geometry triangle solves proportional means obtaining by known theorems height and Hick.
Before stating these theorems and deduce, recall some basic concepts of proportionality to understand what it is that we can solve with constructs derived from these geometric models.

El concepto de potencia de un punto respecto de una circunferencia se basa en el producto de la mayor por la menor de las distancias de un punto a una circunferencia.
These distance values are given in the string that contains the center of the circle and the point, namely, in diameter containing said point.
Is it possible to generalize this concept to consider other strings passing through the point P?

Cycles is a new Render Engine for Blender, developed by Brecht van Lommel working for the Blender Foundation.
It is integrated into the user interface from version 2.5, although initially was developped as a “Addon” (added plugin).
The goal of Cycles is to replace the internal rendering engine in the next Blender 2 years old, allowing real time feedback to the designer through the use of the GPU hardware calculation as, instead of the traditional CPU. Veremos cómo seleccionar cycles como motor blender
The loci used to determine the solution of problems with geometric constraints. Among the conditions used are the angular nature and among them the orthogonality.
Given two circles, simply infinite set of circles that intersect orthogonally are grouped in a set called beam circumferences corradicales; These circles are centered on a line called the radical axis.
