      <text><![CDATA[<h3>Points on a circle</h3>

<p>Given a circle with centre \((a, b) \) and radius \(r\), we can determine whether a point \((p,q)\) lies within, outside of, or on the circumference of the circle using the following: </p>

<ol>
<li>\((p−a)^2 +(q−b)^2 < r^2 \iff \) the point lies within the circle.</li>
<li>\((p−a)^2 +(q−b)^2 =r^2 \iff\) the point lies on (the circumference of) the circle.</li>
<li>\((p−a)^2 +(q−b)^2 >r^2 \iff\) the point lies outside of the circle</li>
