If ABC is an isosceles triangle and the coordinates of the base points are B(1, 3) and C(–2, 7). The coordinates of
A can be
- A (1, 6)
- B \(\left(-\frac{1}{8}, 5\right)\)
- C \(\left(\frac{5}{6}, 6\right)\)
- D \(\left(-7, \frac{1}{8}\right)\)
Answer & Solution
Correct Answer
(D) \(\left(-7, \frac{1}{8}\right)\)
Step-by-step Solution
Detailed explanation
Hint: Let \(A(x, y)\) now \((A B)^2=(A C)^2\) except mid point of \(B C\) for \(\triangle A B C\) to be isosceles \(\quad \therefore 8 y-6 x=43\)
