Answer & Solution

Correct Answer

(A) \(\frac{1}{2}\)

Step-by-step Solution

Detailed explanation

Let \(A \equiv(1,1), B \equiv(-2,2), C \equiv(2,-2)\) Slope of \(A B=\frac{-1}{3}\) Slope of \(A C=\frac{-2-1}{2-1}=-3\) Mid point of \(A B=\left(\frac{-1}{2}, \frac{3}{2}\right)\) Mid point of \(A C=\left(\frac{3}{2}, \frac{-1}{2}\right)\) Equation of \(\perp\) bisector of…
