What is the Distance Formula?

Distance formula is one of the most important mathematical tools for calculating distance between two points in coordinate geometry. This fundamental formula allows you to find the exact distance between any two points on a coordinate plane, making it essential for geometry, physics, engineering, and many real-world applications.

How Distance Formula Works

Distance formula is derived from the Pythagorean theorem. When you have two points with coordinates (x₁, y₁) and (x₂, y₂), distance formula helps you calculate the straight-line distance between them. This distance represents the shortest possible path between the two points.

Why Learn Distance Formula?

Understanding distance formula is crucial for success in mathematics and science. Whether you're calculating distance in geometry problems, analyzing data in statistics, or solving physics equations, distance formula provides the foundation for many advanced mathematical concepts.

Understanding the Distance Formula

Learn the mathematical foundation and practical applications of calculating distances between coordinate points.

What is the Distance Formula?

The distance formula calculates the straight-line distance (Euclidean distance) between two points in a coordinate plane. It provides the shortest path measurement between any two coordinate points.

Distance Formula

Where (x₁, y₁) and (x₂, y₂) are the coordinates of two points, and d is the distance between them.

Key Components
d
Distance
The straight-line distance between two points (always positive)
Δx
Horizontal Distance
x₂ - x₁ (difference in x-coordinates)
Δy
Vertical Distance
y₂ - y₁ (difference in y-coordinates)
Square Root
Ensures the result is always positive (distance cannot be negative)
Derivation from Pythagorean Theorem

📐 Pythagorean Theorem

In a right triangle, the square of the hypotenuse equals the sum of squares of the other two sides.

Step-by-Step Derivation:

  1. Place two points P₁(x₁, y₁) and P₂(x₂, y₂) on a coordinate plane
  2. Draw a right triangle with the distance as the hypotenuse
  3. The horizontal leg has length |x₂ - x₁|
  4. The vertical leg has length |y₂ - y₁|
  5. Apply Pythagorean theorem: d² = (x₂-x₁)² + (y₂-y₁)²
  6. Take square root:
P₁P₂|x₂ - x₁||y₂ - y₁|d

🔗 The Connection

The distance formula is simply the Pythagorean theorem applied to coordinate geometry. By treating the horizontal and vertical distances as the legs of a right triangle, we can find the hypotenuse, which represents the straight-line distance between two points.
