Two sides of a rhombus are along the lines, x – y + 1 = 0 and 7x – y – 5 = 0. if its diagonals intersect at (–1, –2), then which one of the following is a vertex of this rhombus ?
A
(–3, –8)
B
C
D
(–3, –9)
Text Solution
Verified by ExpertsThe correct answer is:
B
Sol.
On solving equation of AB & AD
vertex A(1, 2)
A(1, 2)
P is mid point of AC. Hence vertex C is (–3, –6).
So equation of other two sides are 7x – y + 15 = 0 and x – y – 3 = 0.
Hence other vertices are 
and
