Answer:
See below
Step-by-step explanation:
In math, the distance formula gives us the distance between two
points, (x₁, y₁) and x₂, y₂):
[tex]d = \sqrt{(x _{2}-x_{1})^{2} +(y _{2}-y_{1})^{2}}[/tex]
For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is
[tex]d = \sqrt{(1 - (-2))^{2} +(5-1)^{2}}[/tex]
[tex]= \sqrt{3^{2} +4^{2}}[/tex]
[tex]= \sqrt{9 + 16}[/tex]
[tex]= \sqrt{25}[/tex]
= 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.
