Question
Show that the point $\mathbf{Q}(1,-2)$ is equidistant from the points $\mathbf{R}(-11,3)$, $\mathbf{S}(6,10)$, and $\mathbf{T}(1,11)$.
Step 1
Substituting the values, we get: \[ d_{QR} = \sqrt{((-11) - 1)^2 + (3 - (-2))^2} = \sqrt{(-12)^2 + (5)^2} = \sqrt{144 + 25} = \sqrt{169} = 13 \] Show more…
