Question: how to find the distance between two points in rectangular coordinate system?
Answer: The distance formula, d=√(x2−x1)2+(y2−y1)2 d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 , is derived from the Pythagorean theorem and gives us the distance between any two points, (x1,y1) ( x 1 , y 1 ) and (x2,y2) ( x 2 , y 2 ) , in a rectangular coordinate plane.
