K so ive got two coordinates: x1,y1 x2,y2

I want x3,y3 by translating x2,y2 a fixed amount.

Var is type int = 5 for example, the x,y positions can be type double.

How can i do this? Btw i need the generic answer as this must work no matter where x1,y1 and x2,y2 are.

wouldn't it just be (x+variant,y+variant)?

no as what im trying to do is:

z^2 = x^2 + y^2 to get the z distance and add to that then translate it back into x and y distances, which is mathematically impossible, Pythagoras needs 2 lengths, I only have one. Therefore I need some much more advanced way to do this.

ok vilahm since geometry is srs bsns, and from what i understand of your problem shouldnt there just be a number you add to translate the coordinates over say point (1,1) moving to point (3,4) you just make a little right triangle and pythag it up. In your case the hypotnuse of the triangle should be equal to 5

if you want to move the point in a radius of 5 (just a straight line anywhere) then you could also use a distance formula which is essentially the same as pythagoras. I assume this is what you need? I dont fully understand what you are asking

Edit: OK so you want to find the hypotnuse AND the distance to translate it? sounds like there is something else you should be able to find in the problem
