- Let PQR be a right angles isosceles triangle, right angled at P(2,1).
36. Let PQR be a right angles isosceles triangle. right angled at P (2. l). If the equation of I
line QR is 2x + y = 3. then the equation representing the pair of lines PQ and PR is
(a) 3x2 — 3y2 8xy 20s 4 25 = O
(b) +25
(c) 3x2 — 3y2 + 8xy + lox + 15y +20=0
(d) 3x2 — 3y2 — 8xy — lox — 15y — 20 = O
