The opposite angular points of a square are 
and 
. Then the co-ordinates of other two points are
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Obviously, slope of 
.
Let m be the slope of a line inclined at an angle of 
to AC , then 
.
Thus, let the slope of AB or DC be 3/7and that of AD or BC be 
. Then equation of AB is 
.
Also the equation of BC is 
.
On solving these equations, we get, 
.
Now let the coordinates of the vertex D be ( h, k ). Since the middle points of AC and BD are same, therefore 
, 
⇒ ⇒ 
. Hence, 
.
