The radical axis of a pair of circles is defined as the set of points that have equal power h with respect to both circles. For example, for every point P on the radical axis of circles 1 and 2, the powers to each circle are equal: h 1 = h 2. Similarly, for every point on the radical axis of circles 2 and 3, the powers must be equal, h 2 = h 3.
If the radii are equal, the radical axis is the line segment bisector of M 1, M 2. In any case the radical axis is a line perpendicular to ¯. On notations. The notation radical axis was used by the French mathematician M. Chasles as axe radical. [1] J.V. Poncelet used chorde ideale. [2]
Spherical version of Malfatti's problem: [4] The triangle is a spherical one. Essential tools for investigations on circles are the radical axis of two circles and the radical center of three circles. The power diagram of a set of circles divides the plane into regions within which the circle minimizing the power is constant.
Figure 10: The poles (red points) of the radical axis R in the three given circles (black) lie on the green lines connecting the tangent points. These lines may be constructed from the poles and the radical center (orange). Gergonne found the radical axis R of the unknown solution circles as follows.
The intersection of the vertical line on the x-axis at the center of the circle is happenstance of the example illustrated. For solving the cubic equation x 3 + m 2 x = n where n > 0 , Omar Khayyám constructed the parabola y = x 2 / m , the circle that has as a diameter the line segment [0, n / m 2 ] on the positive x -axis, and a vertical ...
Figure 1: The point O is an external homothetic center for the two triangles. The size of each figure is proportional to its distance from the homothetic center. In geometry, a homothetic center (also called a center of similarity or a center of similitude) is a point from which at least two geometrically similar figures can be seen as a dilation or contraction of one another.
