Circle-line Online Search Find Shortest Distance with Ease

Online search is an essential tool in our daily lives, and it has made finding information and solutions faster and easier. One type of online search is a circle-line search, which is used to find the shortest distance between a circle and a line. In this article, we will discuss how to implement a circle-line search to find the shortest distance with ease.

The first step in implementing a circle-line search is to define the circle and line. The circle can be defined by its center point and radius, while the line can be defined by two points. Once the circle and line are defined, we can proceed to the next step, which is to find the intersection points between the circle and the line.

To find the intersection points, we use the quadratic formula, which is a formula used to find the roots of a quadratic equation. In this case, the quadratic equation is the equation of the line and the equation of the circle. Once we have found the intersection points, we can determine which point is closest to the line by calculating the distance between the line and each intersection point.

If the intersection point closest to the line is outside the length of the line segment, then the nearest point on the line is either the starting point or the ending point of the line segment. If the closest intersection point is within the length of the line segment, then the shortest distance is the distance between the line and the closest intersection point.

To summarize, here are the steps in implementing a circle-line search to find the shortest distance:

Define the circle and line

Find the intersection points using the quadratic formula

Determine which intersection point is closest to the line by calculating the distance between the line and each intersection point

If the closest intersection point is outside the length of the line segment, then the nearest point on the line is either the starting point or the ending point of the line segment. If the closest intersection point is within the length of the line segment, then the shortest distance is the distance between the line and the closest intersection point.

In conclusion, implementing a circle-line search to find the shortest distance between a circle and a line can be done with ease. By defining the circle and line, finding the intersection points, and calculating the distance between the line and each intersection point, we can determine the shortest distance. This method is especially useful in tasks such as calculating the distance between a point and a road or finding the closest route between two points.
