What are you building when you use a distance formula

See below  

Step-by-step explanation:

In math, the distance formula gives us the distance between two

points, (x₁, y₁) and x₂, y₂):

For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is  

= 5

You are really using Pythagoras' Theorem to find the distance.

When using the distance formula, you are building a right triangle whose hypotenuse connects two given points.  

this doesn't make sense lol
