MCQ
Angle between the pair of lines $x y=0$ is
  • A
    $30^{\circ}$
  • B
    $45^{\circ}$
  • ✓
    $90^{\circ}$
  • D
    $60^{\circ}$
✓

Answer

Correct option: C.
$90^{\circ}$
(C) Given equation of pair of lines is $x y=0$
$\therefore \quad a =0, h=\frac{1}{2}, b=0$
Now, $a + b =0$
$\therefore \quad$ the lines are perpendicular to each other.
$\therefore \quad$ angle between the pair of line is $90^{\circ}$.
