Understanding the Distance Formula in Coordinate Geometry
The distance formula is a fundamental concept in coordinate geometry that allows you to calculate the straight-line distance between two points in a plane. It is derived from the Pythagorean theorem and is widely used in various mathematical and real-world applications.
What Is the Distance Formula?
The distance formula is expressed as:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Where:
- \( (x_1, y_1) \) are the coordinates of the first point.
- \( (x_2, y_2) \) are the coordinates of the second point.
- \( d \) is the distance between the two points.
This formula calculates the length of the hypotenuse of a right triangle formed by the horizontal and vertical differences between the points.
Key Components of the Distance Formula
- Coordinates: The positions of the points in the Cartesian plane.
- Differences: The horizontal and vertical distances between the points.
- Square Root: Ensures the distance is a positive value representing the length.
