How to find the distance between two points using Pythagoras' Theorem??
If you have a right-angled triangle then, you can use Pythagoras's Theorem.

This theory states that if you have the horizontal distance, a, and the vertical distance, b, between points A and B then, the distance AB, c, is simply:

(a^2 + b^2)^(1/2) = AB = c

This formula is more commonly written in the form

a^2 + b^2 = c^2
Say one point is (2,6) and the second point is (5,10) and you’re trying to calculate the distance between the points,
You find the distance between he two X coordinates (5-2=3) and then the two Y coordinates (10-6=4)
You then square the two distances (4^2 + 3^2 = 25)
And then square root the answer = 5
