RADICAL AXIS Meaning and
Definition
-
The radical axis is a geometric term used in mathematics to define the locus of points that have equal power with respect to two given circles in a plane. It is the line that is perpendicular to the line segment joining the centers of the two circles and passes through the intersection points of the circles.
To understand the concept further, consider two circles in a plane. The radical axis is the line that possesses the property that the distances from any point on the line to the two circles are equal. In other words, if a point lies on the radical axis, the powers of that point with respect to the two circles are equal.
The power of a point with respect to a circle is defined as the square of the distance between the point and the center of the circle minus the square of the radius of the circle. Therefore, the radical axis is a line that guarantees the equality of the powers of any point on it with respect to the given circles.
The radical axis has several important properties. Firstly, it always exists, as long as the two given circles intersect. Secondly, it is perpendicular to the line segment joining the centers of the circles. Lastly, the radical axis is invariant under inversion, meaning that if the circles are inverted with respect to a point, the radical axis will remain the same. The radical axis plays a crucial role in various geometrical constructions, especially in problems involving circles and their properties.

Etymology of RADICAL AXIS
The word "radical" in the context of mathematics has its roots in the Latin word "radix", which means "root". In mathematics, a "radical" refers to a mathematical symbol (√) used for expressing roots of numbers or attributes of geometric figures.
The word "axis" comes from the Latin word "axis", which means "axle" or "pivot". In mathematics, an "axis" typically refers to a straight line around which an object, such as a graph or a coordinate system, can be rotated.
When combined, the term "radical axis" in mathematics refers to a straight line that is perpendicular to the line connecting the centers of two given circles. This line passes through the points where the two circles intersect. The word "radical" is used here to denote the geometric relations associated with the "root" of these circles, specifically their intersection points.
