    Pythagorean theorem

    a^2 + b^2 = c^2

    c is the distance btwn 2 points.

    You are basically making a right angle triangle and using the Cartesian coordinates to give you the values for a & b.

    Us the distnace formula:

    it is the square root of the quantity [(x2 - x1)^2 + (y2 - y1)^2]

    where two points are (x1,y1) and (x2,y2)

    Hope this helps!!!

    distance formula: square root( ((x2-x1)^2)+((y1-y2)^2) )

    where x2 y1 etc are the numbers in the points.

    all of that is under the square root sign
