Marks: +1, -0

A pair of straight lilies is passing through the point (1,1). One of the lines makes an angle 0 with the positive direction of X-axis and the other makes the same angle with the positive direction of I-axis. If the equation of the pair of straight lines is
x2 - (a + 2) xy + y2 + a (x + y - 1) = 0 , a ≠ - 2 , then the value of θ is
