. Equation of the bisector of angle B of the triangle ABC is
y = x. If A is (2, 6) and B is (1, 1); equation of side BC is
A. 2x + y – 3 = 0
B. x – 5y + 4 = 0
C. x – 6y + 5 = 0
D. none of these
Best Answer
Ans: B
Sol: Drop a perpendicular on y = x from A. clearly BAA’’ and BA’A’’ will be congruent
AA’’ = A’A’’. Hence image of (2,6,) w. r. t. y = x will give A’ which is (6,2).
Hence (B) is the correct answer.
