### How to get the coordinate point from given distance...

i faced some problem with coordinate points, how can i get the points (x,y) with the given distance. For example, point A(-2,1) point B(1,5). The distance is 5. so, how am i going to get the point which distance is lets say 3 or 10 from point A?? thanks...

### Re: How to get the coordinate point from given distance...

The distance formula is given by
√[(x2-x1)²+(y2-y1)²]
Hence, the point (x,y) will be at distance 5 from A(-2,1) if the point is C(0,2). The point D will be at a distance 5 from B(1,5) if D is (0,3). There are many more such points.
