Distance formula: the distance between two points on a corroding the
plane.
___________________
d= \| (x2 -x1)2. + (y2 - y1)2
Ex. 1)
A (5,2) , B(3,4)
___________________
d= \| (x2 -x1)2. + (y2 - y1)2
_____________
d= \| (3-5) 2 + (4-2) 2
____________
d= \| (-2)2 + ( 2) 2
______
d= \| (4 +4)
___
d= \| 8
d ~ 2.8
Ex 2.)
C (-2, -4) D (1, 3)
____________________
d= \| (x2 -x1)2. + (y2 - y1)2
___________________
d= \| (1 -(-2))2 + (3 -(-4)) 2
_________________
d= \| (1 + 2)2 + (3 + 4)2
___________
d= \| (3)2 + (7)2
________
d= \| 9 + 49
_____
d= \| 58
d~ 7.6
