JEE MATHEMATICS MCQ: PAIR OF STRAIGHT LINES

1 Easy

1 of 1

Application +4 | -1

A B C D

is a rhombus. Its diagonals

A C

and

B D

intersect at the point

M

and satisfy

B D=2 A C

. If the coordinates of

D

and

M

are

(1,1)

and

(2,-1)

respectively, the coordinates of

A

are

View answer and explanation

Correct option: B

(1,-3 / 2)

Option B ((1,-3 / 2)) is correct because it satisfies the geometric conditions of a rhombus, where diagonals are perpendicular and one is twice the length of the other.
