If three points A, B, C in a plane have coordinates (-2,1), (1,6) and (8,1), respectively
the distance between A and B is..?
-------------
It's a right triangle calculation - find the hypotenuse.
AB+=+sqrt%28diffy%5E2+%2B+diffx%5E2%29+=+sqrt%285%5E2+%2B+3%5E2%29+=+sqrt%2834%29
===========
Do the other 2 the same way.
Know this. It will come up often.
