finding the amount of units in a diagnol line?

[poseyjmac]

i know its simple math, i just can't remember how to do it. lets say i have 2 points on my map, and want to see the distance between those 2 points in units but they differ in X and Y.

now i use the block tool as a ruler, and see how many X and how many Y units it takes to get to the points, 200 X and 350 Y, but what do i do with these two values to calculate how many units it is diagnolly? does that make sense?

If I understand correctly you will want to use the pythagorean theorem.

X^2 + Y^2 = H^2
H being the hypotenuse, aka the direct distance between the points X and Y in your case.

So the equation would be:
(200)^2 + (350)^2 = H^2
H^2 = 162500
H = 403 approximately

thanks, i feel like a dummy for not remembering that. hmm can't find the square route function on windows calculator(on advanced mode)
