Best ResponseYou've already chosen the best response.0That's not just some random formula, it's the pythagorean theorem. Start thinking about points on a coordinate plane as really being triangles.

Best ResponseYou've already chosen the best response.0because if you think, you can just about do it in your head the distance between 3 and 4 is 7 the distance between 6 and 5 is 11 so you have a right triangle, one side is 7, the other sides is 11 and the hypotenuse (distance) is \[\sqrt{7^2+11^2}\]

Best ResponseYou've already chosen the best response.0Exactly. Plus, if you understand the concept, you can use that to help you learn new things or solve problems similar, which just knowing the formula can't help you with.
