Question 29 The vertices of a parallelogram in order are A (1, 2), B (4, y), C (x, 6) and D (3, 5). Then (x, y) is (a) (6, 3) (b) (3, 6) (c) (5, 6) (d) (1, 4) Given A(1, 2), B(4, y), C(x, 6), D(3, 5) We know that Diagonals of parallelogram bisect each other So, O is the mid−point of AC & BD Finding mid−point of AC Coordinates of O = ((1 + 𝑥)/2,(2 + 6)/2) = ((1 + 𝑥)/2,8/2) = ((𝟏 + 𝒙)/𝟐,𝟒) Finding mid−point of BD Coordinates of O = ((3 + 4)/2,(5 + 𝑦)/2) = (𝟕/𝟐,(5 + 𝑦)/2) Now, ((𝟏 + 𝒙)/𝟐,𝟒) = (𝟕/𝟐,(5 + 𝑦)/2) Comparing x-coordinate (1 + 𝑥)/2 = 7/2 (1 + x) = 7 x = 7 – 1 x = 6 Comparing x-coordinate 4 = (𝑦 + 5)/2 4 × 2 = y + 5 8 – 5 = y y = 3 ∴ (x, y) = (6, 3) So, the correct answer is (a)
