Given : three vertices of a square are (-5, -2), (2, -2) and (2, 5) taken in order.
To Find : plot these points and find the coordinates of fourth vertex
Solution:
Diagonals of a Square bisect each other
Hence mid points of diagonals is same
fourth vertex = ( x , y)
(-5, -2), (2, -2) , (2, 5) and ( x , y)
=> ( -5 + 2)/2 = (2 + x)/2 => x = -5
( -2 + 5)/2 = ( -2 + y)/2 => y = 5
Hence ( -5 , 5) is fourth vertex
To Plot ( - 5 , - 2)
go 5 unit left of origin and then 2 unit down
(2, -2) go 2 unit right of origin and then 2 unit down
(2, 5) go 2 unit right of origin and then 5 unit up
( -5 , 5) go 5 unit left of origin and then 5 unit up
