What is the Distance Formula?

The distance formula is a fundamental concept in coordinate geometry and algebra used to calculate the straight-line distance between two points in a plane or space. It is derived from the Pythagorean theorem, providing a reliable method for measuring the separation between points with given coordinates.

Distance Formula in 2D (x, y coordinates):

If P1(x1,y1)P_1(x_1, y_1)P1​(x1​,y1​) and P2(x2,y2)P_2(x_2, y_2)P2​(x2​,y2​) are two points in a plane, the distance $d$ between them is given by:

d=(x2−x1)2+(y2−y1)2d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2}d=(x2​−x1​)2+(y2​−y1​)2​

This is exactly what the distance between two points calculator on CalcsHub.com computes instantly.

Distance Formula in 3D (x, y, z coordinates):

For points in 3D space P1(x1,y1,z1)P_1(x_1, y_1, z_1)P1​(x1​,y1​,z1​) and P2(x2,y2,z2)P_2(x_2, y_2, z_2)P2​(x2​,y2​,z2​):

d=(x2−x1)2+(y2−y1)2+(z2−z1)2d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2 + (z_2 – z_1)^2}d=(x2​−x1​)2+(y2​−y1​)2+(z2​−z1​)2​

Distance Formula Step by Step

Understanding the steps behind the distance formula helps reinforce the concept. Here’s a step-by-step approach:

Step 1: Identify Coordinates

Find the coordinates of the two points. For example, consider P1(2,3)P_1(2, 3)P1​(2,3) and P2(5,7)P_2(5, 7)P2​(5,7).

Step 2: Subtract Coordinates

Compute differences:

Δx=x2−x1=5−2=3\Delta x = x_2 – x_1 = 5 – 2 = 3Δx=x2​−x1​=5−2=3 Δy=y2−y1=7−3=4\Delta y = y_2 – y_1 = 7 – 3 = 4Δy=y2​−y1​=7−3=4

Step 3: Square Differences

(Δx)2=32=9(\Delta x)^2 = 3^2 = 9(Δx)2=32=9 (Δy)2=42=16(\Delta y)^2 = 4^2 = 16(Δy)2=42=16

Step 4: Sum and Square Root

d=9+16=25=5d = \sqrt{9 + 16} = \sqrt{25} = 5d=9+16​=25​=5

This distance formula step by step example illustrates the simplicity of finding distances, and you can replicate the process for distance between two points in 3D.

Distance Formula Derivation

The distance formula derivation originates from the Pythagorean theorem. For a right triangle with sides along the x and y axes:

d2=(Δx)2+(Δy)2d^2 = (\Delta x)^2 + (\Delta y)^2d2=(Δx)2+(Δy)2

Taking the square root gives the distance formula. For 3D points, we extend the same principle by including the z-axis.
