Question: The straight lines represented by (y – mx)<sup>2</sup> = a<sup>2</sup> (1 + m<sup>2</sup>) and (y – ...
The straight lines represented by (y – mx)2 = a2 (1 + m2) and (y – nx)2 = a2 (1 + n2) form a-
A
Rectangle
B
Trapezium
C
Rhombus
D
None of these
Answer
Rhombus
Explanation
Solution
y – mx = ± a; y – nx = ± a 1+n2
These are set of parallel line and distance betweenparallel lines are equal. So figure is rhombus.
