We can leverage this fact to find the measure of <strong><span style="color:#8e44ad;">Each Interior Angle of a Regular Polygon</span></strong>. </p>
<p>To find the measure of each interior angle of a regular polygon of $n$ sides, use the formula below:</p>
<p>$$\frac{(n-2)180}{n}$$</p>

<p><em>What is the measure of each interior angle of a regular octagon?</em></p>
<p>$$\frac{(8-2)180}{8}=135°$$</p>
