MHT CET 2023 Mathematics question
Let PQR be a right angled isosceles triangle, right angled at P(2, 1). If the equation of the line QR is 2x + y = 3, then the equation representing the pair of lines PQ and PR is
Answer: (B)
Solution
Since the triangle is right-isosceles with the right angle at P, PQ and PR each make with QR. The slope of QR is . A line of slope makes with it if : , or . So PQ and PR through are
